Error symptom Cause Remedy
The sensor is in the air
and the display shows
0.0 mg/l or 0 % O
2
– No connection between
measuring instrument and sensor
– Cable defective
– No electrolyte in the membrane
head
– Check connection between
measuring instrument and sensor
– Replace and refill the membrane
head (see section 5.3)
The sensor cannot be
calibrated – Contaminated membrane head
– Electrolyte depleted – Replace and refill the membrane
head (see section 5.3).
Subsequently, wait for 30 to
50 min and recalibrate.
The sensor still cannot
be calibrated after
changing the electrolyte
and membrane head – Contaminated electrodes or
sensor toxification
– Clean the electrodes (see
section 5.4)
Leak display appears – Membrane head not screwed on
tight enough
– Hole in the membrane
– Screw membrane head tighter
– Replace and refill the membrane
head (see section 5.3)
Incorrect temperature
display – Temperature sensor defective – Return the sensor
Mechanical damage to
the sensor – Return the sensor
