ION CALIBRATION AND MEASUREMENT (ONLY APPLICABLE FOR pH 2100)
The pH 2100 meter reads ion concentration in ppm, ppt, mg/l, g/l, mmol/l and mol/l units. See Ion setup Program P3.0 (page 43) to select ion concentration units.

Ion calibration

This instrument is capable of up to 5-point custom ion calibration with a minimum of 2-point calibration. Custom calibration values can be any value between 0.001 and 19998. Once the first calibration value is keyed in, all other calibration will automatically be at least one decade apart. For example if your first calibration point is at 0.001, all other calibration points will be at least one decade apart from 0.001 (0.001, 0.01, 0.1,1.0, 10.0, 100, 1000, 10000). For best accuracy calibrate your meter to points with similar concentrations to the solutions you want to test. 1. 2. Connect an Ion Selective Electrode (ISE) to the BNC input connector on the back of the meter. Turn the meter ON. If the meter is not in the Ion measurement mode, press EXIT and use >/CAL to select Ion. The mode selected will flash. See Figure 48. Press ENTER to confirm selection. The meter is now in Ion measurement mode. If the meter has not been calibrated or has been reset, the display will flash Ion Meas and current mV value. See Figure 49. If the meter has been calibrated previously, the display will show the current concentration value plus the absolute mV produced by the electrode. Dip the electrode into the first calibration standard. Start with the calibration standard that has the lowest concentration and move up to higher concentration standards. Press >/CAL to enter the ion calibration mode. The display will flash Cal Mode Activated, Please wait. See Figure 50. The display then shows Ion Conc: ppm (or unit selected in ion setup mode) in the upper display and Abs. mV: in the lower display. See Figure 51. The first calibration point must be keyed in by the user. Key in the concentration value of the standard using the numeric keypad. If you make a mistake, use the /MI or /MR keys to highlight mistake, then re-enter. Press ENTER to confirm the first calibration point. The display will flash 1 Cal Point Done *, then the meter proceeds to the next calibration point at least 1 decade apart from the first calibration point. See Figure 52. Use /MI or /MR keys to move the cursor to next calibration point. All points will be a decade apart from the first calibration point. Rinse off the electrode with deionized water before placing it in the next calibration standard.

Ion calibration error messages
If you leave the ion calibration mode prior to confirming two calibration points by pressing the EXIT key, the screen will flash Error: Cal Aborted. See Figure 56. The meter will revert to back to the earlier calibration curve and return to the ion measurement mode. If the average ion slope is not within 10 to 75 mV per decade, the upper display will flash Error: and the lower display will read Ion Slope Error. See Figure 57.

Ion measurement
The pH 2100 meter features two different modes of ion measurement: high resolution mode and low resolution mode. These modes are user selectable in the Ion setup program P3.4. (page 47). The default is high resolution mode. Low resolution mode should only be used if your ion solution concentration will produce an absolute mV value of 500 mV. 1. Turn the meter ON. If the meter is NOT in the Ion measurement mode, press EXIT and use >/CAL to select Ion. The mode selected will flash. See Figure 58. Press ENTER to confirm selection. The meter is now in Ion measurement mode. If the meter has not been calibrated, or has been reset, the display will flash Ion Meas and current mV value. See Figure 59. If the meter has been calibrated, the display will show the current concentration value plus the absolute mV produced by the electrode. See Figure 60. Prepare samples as necessary. Sample preparations varies depending on ion typesee your electrode manual for details on the specific electrode that you are using. Dip electrode into the sample. The sensor or glass bulb of the electrode must be completely immersed into the sample. Allow time for the reading to stabilize, then record your measurement.

11 ELECTRODE CARE

11.1 Electrode Activation
DO NOT touch or rub the glass bulb. If you follow the storage and maintenance procedure, you can use your electrode immediately. If the electrode responds sluggishly or drifts, the bulb may be dehydrated. Immerse the electrode in an ideal storage solution such as electrode storage solution or pH 4 buffer solution for 1-2 hours to hydrate it. See Storing pH/ORP electrodes below. If this procedure does not hydrate the electrode, reactivate or replace it. Use 2 or 3 point calibration to test your electrode performance. If you do not get good readings, use a different pH electrode to confirm the meter is working properly. If the results are still not satisfactory, consult your distributor/dealer.

12.2 Using with computer

Use OAKTON RS-232 cable 35615-09 to connect your meter to a computer. Refer to enclosed software disc for instructions on how to use software with your meter.
13 ADDITIONAL INFORMATION

13.1 pH and Temperature

The pH electrode is affected by temperature changes. Automatic Temperature Compensation (ATC) compensates for these temperature changes. Some solutions show an increase while others a decrease in pH with the same temperature change. Record the solution temperature along with the pH value, or the measurement may be meaningless. Temperature changes also affect the signal the pH electrode sends to the meter and causes a loss of accuracy for the reading. To limit the loss of accuracy during calibration, make the temperature of the pH buffer calibrating solutions and the sample solution the same.
13.2 pH Buffer Calibration Solution
You can use standard buffer solutions to calibrate a pH meter before you measure the pH of a sample. Calibration solutions serve as basis of comparison between measurements. The most common standard buffers are pH 4.01, pH 7.00 and pH 10.01. For 1-point calibration, use a standard buffer of pH 7.00 or 6.86, or a standard or custom buffer whose pH value is close to that of the sample. Use 2-point calibration when you know the sample is acidic (low pH) or basic (high pH). For example: in acidic samples, use standard buffers such as pH 7.00 and pH 4.01; in basic samples, use standards such as pH 7.00 and pH 10.01. Use multi-point calibration when the sample pH is completely unknown or for best accuracy over the entire pH range. Contact your distributor for information on pH buffer and calibration solutions.

13.3 Standard pH Buffers
