4.2 mV Measurement
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 45. Press ENTER to
confirm selection.
The meter is now in Rel mV measurement mode. See Figure 46. If
you have not performed a mV calibration or have reset the meter,
the display will read Abs. mV. See Figure 47.
2. Dip the electrode into the sample. The sensor or glass bulb of
the electrode must be completely immersed into the sample.
Stir the electrode gently to create a homogeneous sample.
3. Allow time for the reading to stabilize. The upper display will
show the mV reading, and the lower display will show the
current month, day and time. See Figure 46.
