3. Check the device for correct functioning as
follows:
Connect the shorting cap to the BNC input on
the portable meter.
Select mV mode and record the mV value:
Press the [Mode] key
Make sure the portable meter is in mV mode,
not relative mV mode. If the mV value is 0 ± 0.3,
the meter is functioning correctly. Note that the
long-term drift specified for this portable meter
is 0.1 mV/month since the most recent
standardization.
Connect the electrode to the input connector on
the meter (push in and twist to lock). For high-
precision measurements, you can connect an ATC
probe to the ATC port on the portable meter.
4. Rinse and blot-dry electrodes between
measurements (do not wipe). Rinse electrodes
with distilled water, deionized water, or some
of the next solution to be measured.
