Conductivity Calibration Reminder (P7)
– set X hours (H) Or X days (D) in ZenTest mobile app –
settings
– Parameter – pH – Calibration Reminder. On the meter, you can only check the values that’s
been set up on ZenTest App. For example, if 3 days is set up, the Er6 icon (see Figure-4) will appear in
the lower right corner of the LCD screen in 3 days to remind you to perform calibration, also in the
ZenTest App there will be a pop-up reminder. After calibration is finished or the reminder setting is
cancelled in the ZenTest App, the Er6 icon will disappear.
6)
Conductivity Back to Factory Default (P8)
– Select “Yes” to recover instrument calibration to
theoretical value. This function can be used when instrument does not work well in calibration or
measurement. Calibrate and measure again after setting the instrument back to factory default.
