The following messages could occur (shown in order of priority):

Message

Reason

Measure

Err

Serious error that does not
permit any further measuring

−

Send the instrument to
WTW

CAL

Err

No valid calibration exists

−

Calibrate the instrument
again (see also the
chapter,

Calibration

)

0FL

The pH/temperature value lies
outside the measuring range
(Overflow)

−

Check the sensor and
sensor connection

Measured value
flashes

An overflow is present on the
corresponding recorder output

−

Adapt the recorder range

Sensor possibly defective
(only in the SensoLyt 700 and
automatic temperature
compensation)
