Cause
Remedy
– Sensor contaminated
– Clean the sensor
– Measured temperature value
outside the operating conditions
(display of OFL/UFL instead of a
temperature value)
– Keep to the temperature range for
the test sample
– Defective sensor
– Calibration
– Exchange the sensor cap
– Replace the sensor
– Calibration failed
– Recalibrate
– D.O. concentration during zero
point calibration too high.
– Immerse the sensor in an oxygen-
free solution
More information and instructions on cleaning and exchange of
sensors are given in the documentation of your sensor.
Cause
Remedy
– Measured value outside the
measuring range
– Use suitable IDS conductivity sensor
Cause
Remedy
