Troubleshooting
7.1
Error messages
Problem/display screen
Caused by
Action
Communication with probe
The probe is not connected to the
instrument
– Plug in the probe
– Check the connection to the probe
– Correct probe number
EEPROM error
Values cannot be saved
Switch the instrument off and then back
on again
Overflow area
Concentration too high
– Probe is measuring in an unsuitable
medium
– It may be necessary to recalibrate
Clean the probe
Probe is dirty
– Clean the probe
– May be triggered by inhomogeneous
measuring medium
Offset error
Calibration point set incorrectly
(calibration point too close to the zero
point)
Recalibration required
Calibration error
No calibration available, calibration
points set incorrectly (upper and lower
calibration points transposed)
Recalibration required. (1-point default
calibration of DS curves not sufficiently
precise for measuring medium)
Calibration insufficient –
Further calibration point with lower
concentration is missing
Further calibration point with lower
concentration is required
Calibration insuff
Further calibration point with greater
concentration is missing
Further calibration point with greater
concentration required
Probe error
Technical error in the probe
– Switch the instrument off and then
back on again
– If the message is repeated, send the
probe for repair
Battery is empty
Battery not charged
Charge the battery fully
1
Incorrect probe
Probe has been replaced but not
re-registered or correctly registered on
instrument
– Connect the correct probe
– Use code 390 to release DS curve for
new probe and recalibrate
Error time/date
Time/date implausible
– Switch the instrument off and then
back on again
– Check the time/date set
– If required, change the clock
batteries

1
The battery charger must agree with local and national safety regulations and may not be part of the shipment. If the charger is
not part of the shipment, charge the batteries with a charger available in your country. Make sure that the charger agrees the
battery specifications.
2
If the message is repeated, send the instrument for repair
7.2
Informative messages
Display
Caused by
Measure/note
Wait
Calibration is being recorded
Wait (probe in calibration medium)
Manufacturer standard
Measurement value is outside the
standard (only for turbidity)
Value is above the DIN standard of
4000 FNU (NTU)
