record the measurement.
3) After measurement, rinse the probe with distilled water, shake off excess water, and put the
protection cap back on.
4) Storage: Always leave a bit 3M KCL storage solution in the probe cap when storing the meter as it
will optimize the performance and maximize the life of the pH probe.
5) Change temperature unit: When meter is turned off, hold the CAL button until the meter reboots
and then the temperature unit will be switched (˚C–˚F)

4. Notes

1) Calibrate the pH pen at least once a month.
2) To ensure the accuracy, make sure the pH standard buffer is fresh and clean. The small bottle of
V4.3
will appear on the screen.
