Once the AC/DC adapter is connected and powered on,
the meter beeps and the full LCD lights up for a few

To access the meter functions, press ON/OFF key. The
meter beeps and performs a diagnostic test before
going into the pH measurement [MEAS] mode. To turn
the meter off, press ON/OFF key within the operation

IMPORTANT :
Remember to remove the protective cap from
the electrode tip prior to measurement.
Replace it in place after use or store electrode
in some storage solution to avoid possible
dehydration of glass bulb which may result in
slow response.
In any case if the electrode is not in use for
long period, condition the electrode by
soaking into tap water for 1-2 hours before use.
Make sure to wash electrodes/probes
before/after each sample measurements to
prevent any carry-over of samples.
