Tracy Marcial is a Registered Mechanical Engineer with a BS in Mechanical Engineering from the University of California, Los Angeles and an MS in Engineering Management from Santa Clara University. She has over 14 years of energy efficiency work experience including HVAC design, extensive experience with building energy analysis, simulation modeling, measurement and verification, energy auditing, and lifecycle cost analysis. During this time Ms. Marcial worked on a diverse range of projects including commercial buildings, schools and universities, laboratories, clean rooms, hospitals, and warehouse facilities. Ms. Marcials work experience includes energy use and life cycle cost analyses for the purpose of producing economical and energy efficient retrofit recommendations. She has conducted energy audits for several facilities of up to 4,000,000 square feet. Computer models were created during these audits through the use of DOE-2 based energy simulation programs and time-of-day based Excel Spreadsheets. Actual historical utility data and specific measured data were used to develop calibrated computer models of the facilities. The computer models were then used to analyze the economic viability of various energy conservation measures. Upon implementation of energy conservation recommendations, Ms. Marcial assisted clients in receiving incentives from utility companies through the use of Californias Standard Performance Contract (SPC) program and other similar incentive programs. This work included processing necessary application calculations and submittals through the final stages of measurement and verification of achieved savings after the first and second years of operation of the retrofitted system. Ms. Marcial combines practical field experience, excellent engineering fundamentals, and a focus on energy usage to design complete HVAC systems for a wide variety of projects.

ACCEPTANCE TEST PROCEDURE FOR THE TECO 42 OXIDES OF NITROGEN ANALYZER
Volume II Section W.2.0 Revision 0 August 1, 1994 Page 1 of 8 W.2.0 W.2.0.1 PROCEDURE GENERAL INFORMATION - Before beginning acceptance testing of the analyzer, read the manual and ARB purchase specifications thoroughly. Then, initiate an Acceptance Test Log (Figure W.2.0.1) and an Acceptance Test Mini-Report (Figure W.2.0.2). Record the dates of the individual tests, problems, contacts with the manufacturer, and any other pertinent information on the acceptance test log. PHYSICAL INSPECTION - Unpack the analyzer and check for physical damage. Verify that the analyzer is complete and includes all options and parts required by the specifications and purchase order. Remove the top cover from the analyzer and perform the following checks: 1. Make sure that all circuit boards are properly seated in their connectors by removing and reinserting each board. Check for correct power cord phasing; standard wiring configuration has the black wire connected to the brass terminal of the plug, white to the copper terminal, and green to earth ground. Start up the analyzer following the procedures in the manufacturer's manual and verify that all switches and controls operate properly. Leak check the analyzer using appropriate methods for the type of sampling system used. Measure the output of each power supply and record the voltages on the acceptance test mini-report.

W.2.0.2

W.2.0.3
OPERATIONAL CHECKS - Perform the following operational checks using a strip chart recorder connected to the analog output, and record the results on the acceptance test mini-report. Cut the recorder charts in 24-hour segments and label the bottom of the chart with the following: Test performed Date Make, model number, and serial number of test analyzer Range on which test is performed Recorder trace color identification if appropriate NOTE: Record on the strip chart the numerical values of the trace at the indicated point.
Volume II Section W.2.0 Revision 0 August 1, 1994 Page 2 of 8 Clear precise notations should be entered on the chart indicating when the tests were started and ended, pertinent information regarding sample flow, gas concentrations, voltages, interferent gases, etc., and any unusual conditions observed. Tests should be run in the range normally used in field operations. All tests should be run in parallel with a control analyzer and recorder whose charts are labeled as above. 1. Diagnostic and Voltage Test - Record all pertinent diagnostics and measured values on the Diagnostic Test form (Figure W.2.0.3). For example: Diagnostics 2. Information Cooler Temp. EC No span factor Indicated Value -3 0.98
Zero and Span Stability - Using a gas calibrator and an appropriate gas standard (super blend), adjust the zero and span controls of the analyzer for proper response. Manually or by using the calibrator timer program, run zero and span points (80 percent). Repeat the zero and span using the same calibrator settings for 30 days. Record the readings of the zero/span drift on the Linearity Zero/Span Drift Tests form (Figure W.2.0.4). Record the changes in zero and span on the Acceptance Test Mini-Report (Figure W.2.0.2).

Linearity - Using the automatic gas calibrator remote program, perform a linearity test at 80, 40, 20, 10, 8, 6, 4, and 2 percent of full scale. The predicted response is calculated using the responses of the reference analyzer as illustrated by the following table: Reference Net % FS Chart 83.1 41.6 20.5 : : 1.8 Test Net %FS Chart 82.5 41.0 20.6 : : 1.9 Predicted (Calculated) ---41.3 20.4 : : 1.9 Non-linearity %FS (Calculated) ----0.3 +0.2 : : 0.1

20 : : 2

For example, the predicted value at the 40 level = 41.6 x 82.5 = 41.3 83.1
Volume II Section W.2.0 Revision 0 August 1, 1994 Page 3 of 8 The non-linearity at this level is 41.0 - 41.3 = -0.3 percent Record the test results on the Linearity Zero/Span Drift Tests form (Figure W.2.0.4), and transfer the non-linearity numbers to the Acceptance Test Mini-report (Figure W.2.0.2). Compare the results to the purchase specifications. 4. Temperature and Voltage Stability - Place the test analyzer in the Thermotron environmental chamber and connect the analyzer power cord to the variable voltage power strip. Connect the sample inlet to the sample manifold supplied by an automatic calibration system. The reference analyzer should remain external to the chamber operating on normal house power. Initiate a temperature/voltage run using Thermotron program number seven (7) while the test and reference analyzer are sampling zero air. Repeat the temperature/voltage run while the analyzers are sampling a concentration equal to 80 percent of full scale. Titrate 50 percent of the NO during the 80 percent of full scale test. Record the test results on the Temperature/Voltage Test form (Figure W.2.0.5). Compare the responses of the test analyzer to the purchase specifications. Transfer the test results to the Acceptance Test Mini-Report (Figure W.2.0.2). Converter Efficiency - Prior to the test, set the converter efficiency to 100 percent on the TECO 42. Following the test, set the converter efficiency to the value determined by the test. Determine the converter efficiency as described in the QA manual Volume II, Section D.2.0.3. The titration step at 500 ppb (NO2) must be two hours in duration. Use the 0-1000 ppb range and the timer program of the gas calibrator to provide the test concentrations at 0.5 ppm NO2. NOTE: The converter efficiency must be at least 98 percent at the minimum temperature, i.e., for TECO 42, the minimum temperature is 325 +5EC.
Confirm that all recorder charts are properly labeled, the mini-report is complete, and the analyzer meets or exceeds all specifications. Give the test package (mini-report, recorder charts, and log) to your supervisor for review. After the test results have been reviewed and accepted, contact the Administrative Services Division (ASD) property clerk to have a property number assigned and attached to the analyzer, notify the stock clerk that the analyzer completed acceptance testing, complete a move tag, and place the analyzer in the stockroom.

APPENDIX W.3 CALIBRATION PROCEDURE FOR TECO 42 NITROGEN OXIDES ANALYZER
MONITORING AND LABORATORY DIVISION FEBRUARY 2000
Volume II Section W.3.0 Revision 0 February 14, 2000 Page 1 of 19 W.3.0 W.3.0.1 CALIBRATION PROCEDURE INTRODUCTION This calibration procedure employs a set of NIST traceable, certified mass flow controllers which dilute a NIST traceable, certified nitric oxide (NO) gas mixture with zero grade air. The gas dilution system, with these gases, is operated to produce a multi-point "as is", and, if necessary, a multi-point "final" calibration. This document describes the procedure using portable, certified mass flow meters, a blended gas cylinder, and a certified ozone photometer. The same procedures may be followed at ARB sites with a certified NIST 9100 Environics calibrator; the 9100 serves as the transfer standard. The NOx analyzer is calibrated when known concentrations of NO and NOx are entered into the analyzer until readings stabilize. The calculated gas quantity from the calibration system is entered on the NOx analyzers input thumbhole. The STAT button is pushed until the display shows the level of the gas being calibrated. When the CAL button is pushed followed by ENTER, the appropriate NO or NOx channel is calibrated. The ENTER button must also be pushed while the display reads STORE to save the calibration value in the event that there is a power failure. W.3.0.2 APPARATUS NIST traceable nitric oxide gas mixture (@50 ppm) Gas calibration system Set of certified 4-in-1 mass flow meters (MFMs) Calculator capable of linear regression Calibration forms (MLD 47A) or Computer Forms (Quattro Pro or Excel Spreadsheets) Tool kit Data logger and a chart recorder Clean Air Package or Aadco Air Purifier Stainless Steel gas regulator, CGA 660. Timer/stopwatch All connections between components in the calibration system should be made of glass, Teflon, or other non-reactive materials. W.3.0.3 INSTRUMENT CALIBRATION 1. Initial Setup - This procedure follows the calibration guidelines in Section 3 (page III-2) and Section 4 (pages IV-1 through IV-14) of the ThermoEnvironmental (TECO) 42 manual.
Volume II Section W.3.0 Revision 0 February 14, 2000 Page 2 of 19
Plug in the (MFMs) flow transfer standards. They should warm up for at least one hour. Plug in the Calibrator and turn on the power switch. Let the instrument warm up for at least one hour. Place the stainless 660 CGA regulator on the NO cylinder. Purge the calibration gas through the regulator three times before use. This will reduce NO2 contamination. Connect the Dasibi gas calibration system to the TECO 42 and the gas standard. Place the output tubing of the gas calibration system onto the inlet of the NO inline particulate filter. Place a cap on the NO glass manifold inlet.

Calibration System Connection a. Connect zero air to the calibration system and adjust the air pressure to the manufacturers specifications. Purge the gas calibration system with zero air at a flow rate of 5 liters per minute while the gas calibration system warms up.
Data Recording Preparation a. b. Disable the data logger for the NOx, NO, and NO2 channels. Prepare all the headings and other information on the hardcopy calibration forms (Ref. Figure W.3.0.1-3) or alternately, on the laptop computer spreadsheet form (Ref. Figure W.3.0.2, Quattro Pro or Excel).
Analyzer Flow Checks- Other than routine daily checks, analyzer repairs or adjustments should not be made prior to the as is calibration. a. With the 4-in-1 flow transfer standard, check the TECO 42's flows. Disconnect the 1/4 Swagelock connection for the ozone flow. (If the dry air flow is not available from the rear of the instrument, the flow should be plumbed to make this possible.) This port is labeled "Dry Air" in the back of the instrument. Connect this port to the 1-liter or 3-liter flow standard. Record the flow standard's display. Determine the flow by using the certification equation for this flow standard. The ARB units were modified to a
Volume II Section W.3.0 Revision 0 February 14, 2000 Page 3 of 19 nominal flow of 200+ 50 cc/minute. c. Record the rotameter flow from the front of the instrument. Reconnect the filter after the flow check is complete. Check the rate of the analyzer's "Sample" flow. Disconnect the 1/4 Swagelock connection for the sample flow. This port is labeled "Sample" in the back of the instrument. Connect this port to the 1-liter or 3-liter flow standard. Record the MFM's display. Determine the standard flow by using the certification equation for the flow standard. The nominal flow of this port is 700 cc/minute. Record the rotameter's flow from the front of the instrument. Reconnect the sample inlet line after the flow check is complete.

W.3.0.4

AS IS CALIBRATION 1. Initial Checks a. Before performing an "as-is" calibration, ensure that the particulate filter on the sample inlet line has been recently changed. If not, replace it. Verify the analyzer has recently been electronically Zero and Span checked on all three channels. Adjust, if necessary, to ensure the analyzers output is properly aligned.
Zero Calibration Checks a Allow the gas dilution system to operate for at least 30 minutes with zero air flowing at 5-6 LPM. A timer/stopwatch can be used to meter the time between calibration steps. Read and record the zero readings from the NO and NOx channels of the data logger.

Span Calibration Checks a. At the discretion of the person performing the instrument calibration, one of two procedures may be used. The selection of the appropriate procedure depends on the analyzer response to the first point test span gas.
Volume II Section W.3.0 Revision 0 February 14, 2000 Page 4 of 19
Run one (1) as-is calibration point at approximately 80 percent of the upper range limit (URL). Allow sufficient time for the analyzer response to stabilize. If the analyzer response is within +10 percent of true and meets requirements of Table W.3.0.1, do the following: Record the as-is results on the as-is calibration form. Indicate on the bottom of the raw datasheet that the response was within 10 percent of true for the initial 80 percent level. After the response of this first point has been recorded, the person doing calibration may select one of the following procedures: c or d. If the analyzer is operating normally, previous nightly spans indicate no abnormality, and there are no other indications of malfunctions, the analyzer may be re-spanned to reflect the true gas concentration. To make a span adjustment, follow the instructions found in Section W.3.0.6, items 3 and 4. As an alternative, a multi-point as-is calibration may be completed for the following steps 4a through f.
Complete As-Is Calibration - Perform the instrument as-is linearity calibration by completing a multi-point calibration. a. Run four (4) "as is" calibration points. Determine the calibration set points by the following formula: NO ppm = G x C G+A where: G = the flow of gas in cc/m, A = the flow of air in cc/m and, C = the concentration, in ppm, of the NO gas standard b. These calibration points should be approximately 80 percent, 40 percent, 20 percent, and 10 percent of the upper range limit (URL). For example, if the full-scale output of the NO/NOx analyzer is 1.0 ppm, 80 percent of the URL equals 0.80 ppm NO. Calculate the true NO and NOx values from the cylinder and flow transfer standard certification numbers. Record on the datasheet.
Volume II Section W.3.0 Revision 0 February 14, 2000 Page 5 of 19 Read and record the instrument's output for the 80 percent URL level, after 20 minutes or a stable reading is indicated on the chart recorder. Repeat this process for the 40 percent, 20 percent, 10 percent, and zero levels on the datasheet. d. Calculate the slope and intercepts for the NO and NOx data with the linear regression equation. Determine the "as is change from previous calibration for the NO and NOx channels. Mark the strip chart recorders with the type of calibration, date and calibrator's name. In addition, record the NO/NO2/NOx calibration in the stations logbook.

W.3.0.5

CONVERTER EFFICIENCY 1. Converter Efficiency Determination - Read and record the converter efficiency (C.E.) from the previous calibration. This information can be obtained by pressing the "STAT" button until "C.E. XX.X" is displayed. a. Perform the converter efficiency test with a value of 100.0 in the "C.E. XX.X" display. To determine the TECO 42's converter efficiency, operate the gas calibration system near.70 ppm NO. The test will be conducted with the same plumbing configuration as in the "as is" calibration; however, one of the dilution system manifold output ports will be connected to the ozone analyzer's input port. Monitor the ozone concentration during the Gas Phase Titration (GPT) to ensure that all of the ozone is consumed in the reaction. The ozone concentration must be less than 90 percent of the NO concentration. Refer to CFR 40, Part 50, Appendix F, for a detailed explanation of the theory behind gas phase titration. An alternate plumbing configuration is also acceptable. This configuration does not use a connection of the ozone photometer to the calibrator manifold. The alternate configuration can be used if prior experience has shown more than 10 percent of the NO concentration remains after the complete titration of the available ozone is stable. If prior experience with the calibrator shows all ozone being consumed

Volume II Section W.3.0 Revision 0 February 14, 2000 Page 6 of 19 during the titration and at least 10 percent NO is left, then note the set points for the mass flow controllers and the ozone generator that produced the desirable test points. c. Follow the steps starting at Section 3.0.5, item 2, for the alternate plumbing configuration, bypassing steps referring to the ozone photometer, (the following steps have been extracted from the Dasibi 5009 Gas Dilution System Manual).
Alternate Converter Efficiency Method a. Set the gas MFC to deliver a NO concentration between 0.60 and 0.80 ppm. Set the airflow rate to 4-6 LPM. Connect one of the Dasibi 5009 dilution system exit ports to the inlet port of the ozone photometer. Operate the 5009 in the "Auto" and "Load" modes. (Refer to the Dasibi 5009CP manual for detailed operating procedures). Turn on the 5009 photometer pump, and adjust the flow rate through the photometer to 1.5 to 2.0 LPM flow rate. Set the Dasibi 5009 thumb wheel Diagnostic switch to 0. Allow the TECO 42 to sample until the NO/NOX response is stable for 15 to 20 minutes. Record the NO and NOx readings from the data logger onto page 2 of Figure 3.0.1, (form MLD-47), or onto Figure 3.0.3 (computer worksheet). Press "Gas Vent" on the 5009 to open the gas vent. Adjust the ozone level control switch to produce an ozone concentration that is approximately 80 percent of the NO concentration and press the OZONE button. This ozone setting will result in a nitrogen dioxide concentration near 0.50 ppm. Set Timer for 15 minutes to allow the ozone reading to stabilize. Set the Latch/Load (L/L) switch to "Latch" Press "Gas Vent" (to close vent)
Volume II Section W.3.0 Revision 0 February 14, 2000 Page 7 of 19
Set timer, wait 15 minutes, and record readings from the data-logger on the converter efficiency form (Figure W.3.0.1, MLD-47, page 2 of 3) or on the computer worksheet (Figure W.3.0.3). NOTE: During GPT, observe the reaction results by monitoring the analyzer NO response at the data logger. Ensure that at least 10 percent of the original NO is left to eliminate destruction of the molybdenum converter by ozone. Allow titration to continue until the analyzer response is stable.
Push the OZONE button to turn ozone production off and allow NO concentration to return to the pre-titration level. Repeat the steps above until GPTs have been completed for more computer efficiency steps if needed. It is suggested that 0.35, 0.25, and 0.90 ppm nitrogen dioxide concentrations be used for the remaining gas phase titration levels. After completion of the GPT testing and after the readings are recorded, the "ozone" switch should be turned off, the ozone thumb wheel is set to "000", and the "Man/Auto" switch is placed in the "manual" position. Leaving the ozone on unnecessarily will decrease the lifetime of the generator's drive board and the U. V. lamp. After all of the readings have been taken, calculate the analyzer's "Average Percent Converter Efficiency". First, calculate the converter efficiency for each point by the following equation: C. E.= (Delta NO - Delta NOx ) X 100 (Delta NO)

Calculate the average converter efficiency. This is achieved by summing the converter efficiencies for each point, then dividing this result by the number of converter efficiency points. If the converter efficiency is less than 96 percent, a corrective action must be taken. For a detailed description of the GPT theory, see Appendix D, Volume II. Converter efficiency (CE) will be set at 100 percent in the STAT mode. To set the converter efficiency to 100 percent, press the STAT
Volume II Section W.3.0 Revision 0 February 14, 2000 Page 8 of 19 button repeatedly until "CE" scrolls onto the screen. Dial the CE value in the thumb wheel at the bottom of the front panel, (i.e., 100.0% = 1000). Press ENTER. W.3.0.6 ZERO AND SPAN CORRECTION 1. Adjustments for Final Calibration - If the TECO 42 has been calibrated previously at this location, and the "as is" calibration is within five percent of "true", and if adjustments have not been made to the analyzer, the "as is" calibration can be used as a "final" calibration. If the instrument is outside of these parameters, it must be set to zero and spanned before a final calibration can be performed (Table W.3.0.2 troubleshooting guide may be used as a reference for certain conditions to determine a possible malfunction). Instrument Zero - The instrument must be in the "AUTO" mode. Run zero air, from the clean air package or Aadco air purifier, through the gas calibration system for approximately 30 minutes or until a stable reading is achieved for 5 minutes. Press the "DISPLAY" button until "1" appears in the leftmost LED display. (1 is the NO channel). Press the Cal button. Enter 0000" on the thumb wheel. Press "ENTER". Repeat this procedure for the NOx channel (3 is the NOx channel). NO Span - Set the Dasibi 1009 or 5009 to approximately 80 percent of the Upper Range Limit (URL) (0.8 ppm) a. Challenge the instrument with this level of gas for 30 minutes or until a steady trace is achieved for at least 5 minutes. The instrument must operate in the "AUTO" mode for at least 300 seconds with a stable reading. Observe the data logger value. Enter the calculated value for the NO concentration on the thumb wheel (4 position set pot). The calculated NO value is based on the NO assay value, the gas calibrator's gas certification value, and the gas calibrator's air certification value. For example, a value of.8 ppm will be entered as "0800" on the thumb wheel switch. Press the "CAL" button. The light above the CAL button will illuminate. Press the "DISPLAY" button until the leftmost LED display reads 1, (1=NO, 2=NO2, 3=NOx). Press "ENTER" and the NO channel set point will be reset to the calculated value for NO. Since the NO/NOx calibration values tend to drift downward as time increases, it is desirable to set the thumb wheel setting @ 2 percent higher than the calculated dilution values., (e.g., If the concentration of NO has been calculated to be 0.782 ppm NO, set the thumb wheel setting to.798 ppm NO.)

Volume II Section W.3.0 Revision 0 February 14, 2000 Page 9 of 19 4. NOx Span a. Press the "DISPLAY" button until the number 3" appears in the leftmost LED display. The instrument must operate in the "AUTO" mode for at least 300 seconds with a stable reading. Press the "CAL" button. Observe the data logger value. Enter the NOx concentration into the thumb wheel switch. Press "ENTER" and the NOx channel set point will be reset to the calculated value for NOx.

Final Calibration Procedure - If the instrument has been re-zeroed, re-spanned, had its converter efficiency changed by greater that 1.0 percent, or a major maintenance operation performed, a "final" calibration must be performed. Fill out the final calibration form or laptop computer form, as much as possible, then begin the actual calibration. Since the basic principle of operation of this sampler is the subtraction of NO from NOx, it is not deemed necessary to calibrate the NO2 channel. The final calibration steps are the same as the asis, but are briefly summarized below. a. Send zero air to the instrument through the gas dilution system. Record zero readings after 20 minutes of zero air or 5 minutes of stable zero readings. Run four (4) final calibration points using the gas calibration system. These points should be at 80 percent, 40 percent, 20 percent, and 10 percent of the URL. Calculate the true NO and NOx values from the cylinder and flow transfer standard certification numbers. Record this data on the datasheet. Read and record the instrument's output, from the data logger, for the 80 percent, 40 percent, 20 percent, and 10 percent levels. Sum the net NOx concentrations and record the data on the datasheet. Sum the net NO and NOx data logger readings (DAS). Calculate the "Percent Deviation from true, for NO and NOx. Record on the datasheet. Calculate the linear regressions for NO and NOx. With the results from the previous calibration report, calculate the "As-is change from previous calibration for the NO and NOx data. Record these percentages on the datasheet. Note any worthy comments at the bottom of the datasheet.

COMPLETION OF CALIBRATION STEPS 1. 2. Enable all appropriate data logger channels. If the station zero air system is used, reconnect the zero air supply, and set the pressure regulator to its pre-calibration setting. Close valve and turn off compressed gas calibration cylinder. Have the station technician initiate the nightly calibration dilution system, and verify that the data produced is within acceptable limits. Plot the results of the calibration using an acceptable spreadsheet program. The indicated data logger readings are on the y axis. The true NO/NOx concentrations will be plotted on the x axis.
