4 mV CALIBRATION AND MEASUREMENT
4.1 mV Calibration
1. Turn the meter ON. If the meter is not in the mV
measurement mode, press EXIT and use >/CAL to select
mV. The mode selected will flash. See Figure 37. Press
ENTER to confirm selection. The meter is now in absolute
mV measurement mode. See Figure 38.
2. Rinse the electrode in deionized water or rinse solution.
Do not wipe the electrode dry. Wiping the probes
causes static, and will create calibration and
measurement instability.
3. Select your standard and pour into a clean container.
4. Dip the probe into the standard. The end of the probe
must be completely immersed into the sample. Stir the
probe gently to create a homogeneous sample.
5. Press >/CAL key to enter the mV calibration mode. The
display will read Cal Mode Activated, Please wait... See
Figure 39. The meter is now in mV calibration mode. The
upper display shows Abs. mV: and lower display shows
Key in Std: See Figure 40.
NOTE: In mV calibration, the value shown in the upper
display is the same as the lower display.
6. Key in the mV value to match the standard value using
the numeric keypad. If you make a mistake, use the /MI
or /MR to highlight mistake, then re-enter.
7. Press ENTER key to confirm the reading. The display
flashes mV Cal Completed, mV Offset: (shows the mV
offset value). See Figure 41. It then flashes Sys
Updating... Please wait.... The meter returns to mV
measurement mode. The upper display now reads Rel.
mV. See Figure 42.
NOTE: New mV calibrations will override existing the stored
mV calibration data. The meter retains stored mV calibrations
even when the meter is turned off.
To exit from mV calibration mode at any point without
confirming calibration, DO NOT press ENTER in step 7. Press
EXIT.
The upper display then flashes Error: Cal Aborted.
See Figure 43.
4.1.1 mV Calibration error message
If the offset adjustment of your mV calibration is not within ±150.0 mV; the upper display will flash Error: and the lower
display will read mV Offset too large. See Figure 44. Press EXIT to clear error message and return to mV measurement
mode.
