5.5 Calibration reminder
In order to perform accurate measurements, it is necessary to periodically repeat the calibration
process. How often this is necessary will depend on the application and the chemical composition of
the samples measured.
To ensure that periodic calibrations take place on time for any specific application, it is possible to set
a user defined calibration reminder time after which a notification is displayed on the main screen.
It is always advisable, after a series of measurements have been performed, to place the probe in a
relevant pH buffer solution to check that the calibration is still accurate. The deviation of the displayed
value from the buffer solution value will provide an indication if, and how much, drift occurred during
the measurements. If this drift is too large, it may be necessary to repeat the measurements with
intermediate calibrations.
To set or change the calibration reminder:
Go to the Calibrate menu,
and choose Calibration reminder.
Toggle the on/off button and select the
calibration reminder time between 1
minute and 60 hours.
Confirm and apply with the Set button, or exit
with the Back button to discard any changes.
The Calibration reminder setting appears as a notification on the Home screen.

After a new power-up or after (re-)connecting a probe, there will be an automated calibration
reminder always, despite the manual calibration reminder setting.
