Front Panel Operation Introduction

4-1. Introduction

The 5500A Calibrator is capable of supplying lethal voltages. Do not make connections to the output terminals when any voltage is present. Placing the instrument in standby may not be enough to avoid shock hazard, since the operate key could be pressed accidentally. Press the reset key and verify that the 5500A Calibrator is in standby before making connections to the output terminals. This chapter presents instructions for operating the 5500A Calibrator from the front panel. For a description of front panel controls, displays, and terminals, see Chapter 3, Features.
4-2. Turning on the Calibrator
To avoid electric shock, make sure the 5500A Calibrator is safely grounded as described in Chapter 2. W Caution Before turning the 5500A Calibrator on, make sure that the line voltage selection is set properly. Refer to Selecting Line Voltage in Chapter 2 to check the line voltage setting. When the 5500A Calibrator is powered, the initial display is Starting Up. (see below) and it completes a self-test routine. If a self-test fails, the Control Display identifies an error code. For a description of error codes, see Chapter 7, Maintenance.

Starting up.

After self-test, the Control Display shows the reset condition (below).

330 mV auto

auto locked
For a discussion of the softkey selection shown above (auto/locked), see Auto Range Versus Locked Range later in this chapter.
4-3. Warming up the Calibrator
When you turn on the 5500A, allow a warm-up period of at least 30 minutes for the internal components to stabilize. This ensures that the calibrator meets or exceeds the specifications listed in Chapter 1. If you turn the 5500A Calibrator off after warm-up and then on again, allow a warm-up period of at least twice the length of time it was turned off (maximum of 30 minutes). For example, if the calibrator is turned off for 10 minutes and then on again, allow a warm-up period of at least 20 minutes.

Note At voltage outputs of 100 volts and above (nominal), you may notice a slight high-pitched sound. This is normal. 5. Press a multiplier key, if necessary. For example, press c. 6. Output in volts Press V. Output in dBm Press bV. 7. The Control Display now shows the amplitude of your entry. For example, 2.44949 V (below).

2.44949 V

8. Press the numeric keys and decimal point key to enter the desired frequency output (maximum five numeric keys). Press a multiplier key, if necessary. For example, press the kilo multiplier key K. Then press the H key. For example, 1.1234 kHz (below).

2.44949 V 1.1234 kHz

2.44949 STBY 1123.4
Several softkey labels appear on the Control Display in the ac voltage function, depending on which waveform is selected: DUTY, OFFSET and WAVE.

DUTY 50.00

OFFSET +0.00000

WAVE square

1.00 to 99.00%
See sine specifications. tri square truncs
DUTY (Duty Cycle) When the squarewave is selected, DUTY appears, allowing you to modify the duty cycle of the squarewave. The range is 1.00 to 99.00%. The default is 50.00%. The duty cycle must be 50.00% if you want to enter an OFFSET (see below). OFFSET (Voltage Offset) Appears when the desired output is less than 33V (sinewaves), 65 V (squarewaves) or 93 V (trianglewaves and truncated sinewaves). This softkey allows you to add a positive or negative dc offset voltage to the ac output signal. See Entering a DC Offset later in this chapter for more information. When a voltage output is expressed in dBm, voltage offset is not available. You can enter an offset for a squarewave output only when the duty cycle is 50.00% (see DUTY above). WAVE (Waveform) Allows you to select one of four different types of waveforms: sinewave, trianglewave, squarewave, and truncated sinewave. (See Waveform Types later in this chapter for more information). Whenever a non-sinusoidal waveform is selected, the Output Display shows Pp (peak-to-peak). Waveform is not available for a sinewave output in dBm instead of volts.
4-23. Setting DC Current Output Complete the following procedure to set a dc current output at the 5500A front panel AUX terminals (or 5725A Amplifier BOOST terminals if a 5725A is connected). If you make an entry error, press G to clear the display, then reenter the value.
1. Press R to clear any output from the 5500A. 2. Connect the UUT as described earlier in this chapter under Connecting the Calibrator to a UUT. 3. Set the UUT to measure dc current on the desired range. 4. Press the numeric keys and decimal point key to enter the desired current output (maximum six numeric keys). For example, 234.567. 5. Press I to select the polarity of the current (default is +). 6. Press a multiplier key, if necessary. For example, press c. 7. Press A 8. The Control Display now shows the amplitude of your entry. For example, 234.567 mA (below).

7. Press E. The calibrator clears your entry from the New pf = line and copies it to the Power Factor = line of the Control Display. 8. Press P one or more times to return to previous menus.
4-43. Entering a DC Offset
When the calibrator single output is an ac voltage of sinewaves, trianglewaves, squarewaves or truncated sinewaves, you can apply a +dc offset. When applying an offset to squarewave outputs, the duty cycle must be 50.00% (default). The offset selection is entered using the softkey OFFSET, which appears when the ac voltage output is less than 33 V (sinewaves), 66 V peak-to-peak (squarewaves) or 93 V peak-topeak (trianglewaves and truncated sinewaves). The softkey OFFSET will not appear and offsets may not be entered when the output is a voltage sinewave measured in dBm. The maximum offset value allowed depends on the maximum offset and maximum peak signal for each range. For example, a squarewave output of 10 V peak-to-peak is within the range 6.6 to 65.9999 V peak-to-peak, a range that allows a maximum peak signal of 55 V. For this example, the squarewave peak value is 5 V, thus allowing a maximum +offset of 50 V for a maximum peak signal of 55 V. Check the specifications in Chapter 1 for offset limits. If you are using an offset voltage and you cause the output to move into a range where offset is not allowed (for example, above 33 V for a sinewave output), the calibrator will go into the standby mode and the offset function will be disabled. Complete the following procedure to enter a dc voltage offset. If you make an entry error, press G to clear the display, then reenter the value. This procedure assumes you have already sourced a single ac voltage output not exceeding 33 V (sinewaves), 65 V peak-to-peak (squarewaves) or 93 V peak-to-peak (trianglewaves and truncated sinewaves), thus displaying the softkey OFFSET (below).
1. Press the softkey WAVE to select the desired waveform: sinewaves (sine), trianglewaves (tri), squarewaves (square) or truncated sinewave (truncs). 2. Press the softkey OFFSET, opening the offset entry display. Enter the desired offset using the numeric keys and decimal point key. For example, 0.123 V (below).

Offset = +0.0000 V New offset = 0.123 V
3. Press the E key to enter the offset and then P.
Front Panel Operation Using the 5725A Amplifier
4-44. Using the 5725A Amplifier
The 5725A Amplifier increases the current and voltage bandwidth, and drive capability of the 5500A Calibrator. The 5725A Amplifier has separate voltage boost and current boost amplifiers, however, only one boost function can be used at any one time. When operated in dual output modes such as ac power, the 5725A Amplifier can supply one output, while the 5500A Calibrator supplies the other output. In the voltage boost mode, the 5725A output appears on the 5500A Calibrator NORMAL terminals. In the current boost mode, the 5725A output appears on the 5725A CURRENT OUTPUT terminals. You can also redirect 5500A current to the 5725A output terminals; 0 - 2.2 A dc, and 300 A - 2.2 A ac. The Output Display on the 5500A always shows the actual output of the amplifier, not the excitation output of the 5500A. Rules of Operation Whenever the 5500A Calibrator front panel B key annunciator is on, either the 5725A voltage boost amplifier or current boost amplifier is in use. The 5725A Amplifier front panel indicators identify which amplifier is operating. If the 5725A Current Amplifier indicator is on, while the 5500A B annunciator is off, 5500A current is being directed to the 5725A terminals. During this condition, both the 5725A voltage boost and current boost amplifiers are disabled. When sourcing current, the output softkey choice AUX (5500A) or BOOST (5725A) takes precedence over the Source Preference softkey and the front panel B key. Exception: When the selected current cannot be sourced by the 5500A (e.g., 10 A, 15 kHz), the output automatically switches to BOOST and displays error 540 in the Control Display (Current OUTPUT moved to 5725A). The Source Preference softkey in the SETUP menu chooses the 5500A Calibrator or 5725A Amplifier when either can source the selected output. The B key is a temporary Source Preference selection. Toggling B on sets the Source Preference to the 5725A. Toggling B off sets the Source Preference to the 5500A. Pressing R reestablishes the default Source Preference stored in the non-volatile memory. Any current or voltage combination that is outside the capabilities of the 5500A Calibrator but within the capabilities of the 5725A Amplifier, will automatically activate the 5725A Amplifier output. Selecting a 5725A Amplifier boost current between 1.5 - 2.19999 A: Enter the desired current. Select boost with the OUTPUT softkey. Verify source preference is 5725. Verify the B annunciator is on. The boost current appears on the 5725A CURRENT OUTPUT terminals. Selecting a 5725A Amplifier boost current > 2.2 A: Enter the desired current. Select boost with the OUTPUT softkey. (Source preference unimportant) Verify the B annunciator is on (and cannot be toggled off) The boost current appears on the 5725A CURRENT OUTPUT terminals.

5-56. Output Queue The output queue is loaded whenever a query is processed, and holds up to 800 characters. The controller reads it with a statement such as a BASIC INPUT statement, removing what it reads form the queue. If the queue is empty, the 5500A Calibrator does not respond to the INPUT statement from the controller. The Message Available (MAV) bit in the Serial Poll Status Byte is 1 if there is something in the output queue and 0 if the output queue is empty.

Remote Program Examples

5-57. Error Queue When a command error, execution error, or device-dependent error occurs, its error code is placed in the error queue where it can be read by the ERR? command. (See Appendix F for a list of error messages.) A way to decode an error code is to send the command, EXPLAIN?, which returns a description of a error code. Reading the first error with the ERR? command removes that error from the queue. A response of 0 means the error queue is empty. The Error Available (EAV) bit in the Serial Poll Status Byte indicates whether the queue is empty. The error queue is cleared when you turn off the power, and when you use the *CLS (Clear Status) common command.
The error queue contains up to 16 entries. If many errors occur, only the first 15 errors are kept in the queue. A 16th entry in the queue is always an "error queue overflow" error, and all later errors are discarded until the queue is at least partially read. The first errors are kept, because if many errors occur before the user can acknowledge and read them, the earliest errors are the most likely to point to the problem. The later errors are usually repetitions or consequences of the original problem.
5-58. Remote Program Examples
The following programming examples illustrate ways to handle errors, to take measurements, take a number of successive readings, lock the range, and calibrate the calibrator. These excerpts from programs are written in DOS BASIC.
5-59. Guidelines for Programming the Calibrator Commands are processed one at a time as they are received. Some commands require a previous condition be set before the command will be accepted by the 5500A Calibrator. For example, the waveform must be SQUARE before the DUTY command will be accepted. Using the following programming guidelines will insure that the output is programmed to the desired state.
All external connections commands should be programmed first. The calibrator will be placed in standby and the output may be changed to accommodate the new external connection. The setting may be set even if the present output does not use the setting (for example, setting the current post while sourcing voltage). The output and output mode should be programmed next with the OUT command. All other output parameters such as impedance compensation, offset, and waveforms should be programmed next. The DUTY command must follow the WAVE command. The error status should be checked with the ERR? command. The calibrator will not process the OPER command if an unacknowledged error exists. Finally, the calibrator should be placed in operate with the OPER command.

Return 5725A, 5500A-SC when the 5725A Amplifier option is attached and the Oscilloscope Calibration Option is installed.
OUT x IEEE-488 x RS-232 x Sequential x Overlapped x Coupled Sets the output of the 5500A Calibrator and establishes a new reference point for the error mode. If only one amplitude is supplied, the 5500A Calibrator sources a single output. If two amplitudes are supplied, the 5500A Calibrator sources two outputs. The second amplitude will be sourced at the AUX terminals for dual voltage outputs. If the frequency is not supplied, the 5500A Calibrator will use the frequency that is presently in use. To source or measure a temperature, select the desired sensor and sensor parameters first. (See the TSENS_TYPE, RTD_*, and TC_* commands.) To source a signal using the 5500A-SC option, refer to the SCOPE command in Chapter 8. If you change the frequency of an ac function and the harmonic output is not explicitly set at the same time with the HARMONIC command, the harmonic will be set to 1. Use multipliers e.g., k, M, with the OUT command, as desired.

9-2. Rack Mount Kit

The Y5537 rack mount kit provides all the hardware necessary to mount the 5500A on slides in a 24-inch (61 cm) equipment rack. Instructions are provided in the kit. (To rack mount the 5725A Amplifier, order kit Y5735.)
9-3. IEEE-488 Interface Cables
Shielded IEEE-488 cables are available in three lengths (See Table 9-1). The cables attach to the 5500A to any other IEEE-488 device. Each cable has double 24-pin connectors at both ends to allow stacking. Metric threaded mounting screws are provided with each connector. Appendix D shows the pinout for the IEEE-488 connector.
9-4. RS-232 Null-Modem Cables
The PM8914/001 and RS40 null modem cables connect the 5500A SERIAL 1 FROM HOST port to a printer, video display terminal, computer, or other serial device configured as DTE (Data Terminal Equipment). Appendix D shows the pinouts for the serial connectors.

9-5. RS-232 Modem Cables

The 943738 modem cable connects the 5500A SERIAL 2 TO UUT port to a unit under test serial port (with DB-9 male connector). Appendix D shows the pinouts for the serial connectors.

9-6. 5500A/LEADS

The optional test lead kit, 5500A/LEADS, consists of four high-voltage safety leads (red, black, white, yellow), thermocouple extension wires, thermocouple miniconnectors, and thermocouple measuring beads.
9-7. 5725A Amplifier Accessory
The Fluke 5725A Amplifier is an external unit operating under 5500A Calibrator control to extend the volt/hertz and voltage compliance capability of the calibrator. The amplifier adds the following capabilities to the calibrator with no compromise in accuracy: Frequency limits at higher voltage increase to 100 kHz at 750 V, 30 kHz at 1100 V. Load limit increased to 70 mA for frequencies above 5 kHz Capacitive drive increases to 1000 pF, subject to the maximum output current.
A separate set of binding posts on the front panel of the 5725A supplies extended capability. Since most meters have a separate input terminal for the high current ranges, this eliminates the need to change cables during a procedure.

Glossary

adc (analog-to-digital converter) A device or circuit that converts an analog signal to digital signals. absolute uncertainty Uncertainty specifications that include the error contributions made by all equipment and standards used to calibrate the instrument. Absolute uncertainty is the numbers to compare with the UUT for determining test uncertainty ratio. accuracy The degree to which the measured value of a quantity agrees with the true (correct) value of that quantity. For example, an instrument specified to +1% uncertainty is 99% accurate. apparent power The power value obtained by simply multiplying the ac current by the ac voltage on a circuit without consideration of any phase relationship between the two waveforms. (See true power for comparison.) assert To cause a digital signal to go into a logic true state. af (audio frequency) The frequency range of human hearing; normally 15 - 20,000 Hz. artifact standard An object that produces or embodies a physical quantity to be standardized, for example a Fluke 732A dc Voltage Reference Standard. base units Units in the SI system that are dimensionally independent. All other units are derived from base units. The only base unit in electricity is the ampere.
buffer 1. An area of digital memory for temporary storage of data. 2. An amplifier stage before the final amplifier. burden voltage The maximum sustainable voltage across the terminals of a load. compliance voltage The maximum voltage a constant-current source can supply. control chart A chart devised to monitor one or more processes to detect the excessive deviation from a desired value of a component or process. crest factor The ratio of the peak voltage to the rms voltage of a waveform (with the dc component removed). dac (digital-to-analog converter) A device or circuit that converts a digital waveform to an analog voltage. dBm A reference power level of 1 mW expressed in decibels. derived units Units in the SI system that are derived from base units. Volts, ohms, and watts are derived from amperes and other base and derived units. displacement power factor Refers to the displacement component of power factor; the ratio of the active power of the fundamental wave, in watts, to the apparent power of the fundamental wave, in voltamperes. distortion Undesired changes in the waveform of a signal. Harmonic distortion disturbs the original relationship between a frequency and other frequencies naturally related to it. Intermodulation distortion (imd) introduces new frequencies by the mixing of two or more original frequencies. Other forms of distortion are phase distortion and transient distortion. errors The different types of errors described in this glossary are offset error, linearity error, random error, scale error, systematic errors, and transfer error. flatness A measure of the variation of the actual output of an ac voltage source at different frequency points when set to the same nominal output level. A flat voltage source exhibits very little error throughout its frequency range.

thermocouple Two dissimilar metals that, when welded together, develop a small voltage dependent on the relative temperature between the hotter and colder junction. traceability The ability to relate individual measurement results to national standards or nationally accepted measurement systems through an unbroken chain of comparisons, i.e., a calibration audit trail. Measurements, measurement systems or devices have traceability to the designated standards if and only if scientifically rigorous evidence is produced in a continuing basis to show that the measurement process is producing measurement results for which the total measurement uncertainty relative to national or other designated standards is qualified. transfer error The sum of all new errors induced during the process of comparing one quantity against another. transfer standard Any working standard used to compare a measurement process, system, or device at one location or level with another measurement process, system, or device at another location or level. transport standard A transfer standard that is rugged enough to allow shipment by common carrier to another location. true power The actual power (real power) used to produce heat or work. Compare to apparent power. true value Also called legal value, the accepted, consensus, i.e., the correct value of the quantity being measured. uncertainty The maximum difference between the accepted, consensus, or true value and the measured value of a quantity. Uncertainty is normally expressed in units of ppm (parts per million) or as a percentage. units Symbols or names that define the measured quantities. Examples of units are: V, mV, A, kW, and dBm. See also SI System of Units. UUT (Unit Under Test) An abbreviated name for an instrument that is being tested or calibrated. var Symbol for voltampere reactive, the unit of reactive power, as opposed to real power in watts.
verification Checking the functional performance and uncertainty of an instrument or standard without making adjustments to it or changing its calibration constants. volt The unit of emf (electromotive force) or electrical potential in the SI system of units. One volt is the difference of electrical potential between two points on a conductor carrying one ampere of current, when the power being dissipated between these two points is equal to one watt. voltage guard A floating shield around voltage measurement circuitry inside an instrument. The voltage guard provides a low-impedance path to ground for common-mode noise and ground currents, thereby eliminating errors introduced by such interference. watt The unit of power in the SI system of units. One watt is the power required to do work at the rate of one joule/second. In terms of volts and ohms, one watt is the power dissipated by one ampere flowing through a one-ohm load. working standard A standard that is used in routine calibration and comparison procedures in the laboratory, and is maintained be comparison to reference standards. zero error Same as offset error. The reading shown on a meter when an input value of zero is applied is its zero or offset error.
