Remedy
Replace the batteries.
Check whether the measurement conditions
correspond to the adjusted measuring range.
Thoroughly rinse the sensor and recalibrate.
If this does not help, replace the sensor.
Enter nominal cell constant or calibrate the
sensor using a known solution.
Check if the opening for the pressure sensor
located on the back of the device is blocked.
Use a buffer solution with a different nominal
value before starting the next calibration step.
Repeat calibration.
Leave the sensor in the liquid until the mea-
sured value is stable. If this does not help,
replace the sensor.
Set the date and time.
Restart, reset to factory settings, configure and
calibrate. If the error occurs again, contact the
Service.
Data error, measurement with analog sensors
no longer possible. Contact the Service team.
Connect operational Memosens sensor.
Re-enter the buffer table (Paraly SW 112).
Clear the logger completely or partially.
Clear the MemoLog completely or partially.
