Description and Resolution
Measurement limits are activated in the menu settings and
measured value is outside these limits.
Check the sample.
Check sample temperature.
Make sure that the pH electrode wetting cap has been
removed and that the electrode is properly connected and
placed in the sample solution.
Max. 500 measurement data can be stored in the memory.
Delete all or partial data in the memory, otherwise you will
not be able to store new measurement data.
Calibration reminder has been switched on in the menu settings
and last calibration has expired.
Calibrate the electrode.
Deleting the calibration data of the selected sensor ID is not
possible, because it is currently the active sensor ID in the meter
shown on the display.
Enter new sensor ID in the menu settings.
Select another sensor ID from the list in the menu settings.
Meter cannot recognize the buffer or standard/buffer has been
used twice for calibration/two buffers differ less than 60 mV.
Make sure that you have the correct buffer and that it is fresh.
Make sure that the buffer has not been used more than once
during the calibration.
The calibration result is outside the following limits: Slope < 85%
or > 105%, Offset < -35 mV or > + 35 mV.
Make sure that you have the correct buffer and that it is fresh.
Check mV signal of electrode, clean or replace the electrode,
The ATC measured temperature is out of pH calibration buffer
range: 5 ... 50 °C.
Keep the buffer/standard temperature within the range.
Change the temperature setting.
ATC measured temperature differs by more than 0.5°C from the
user-defined value/temperature range.
Keep the buffer/standard temperature within the range.
Change the temperature setting.

meter. Reconnect the ISM
The lifetime of the optical DO sensor cap of 1 year has expired.
Change the cap following the instructions of the optical DO
sensor maintenance.
The cap of the optical DO sensor is missing or not installed
properly
- Install a new DO cap onto the optical DO sensor following the
instructions of the optical DO sensor maintencance
- Remove the cap and reconnect it following the instructions of
the optical DO sensor maintenance
There is no signal from the sensor. Switch off the instrument,
reconnect the sensor and try again.
