Fault and System Messages

Display Description
No sensor
Battery voltage too low,
device will only continue operation
for a short time
Battery voltage low
In case of mains op.: wrong voltage
- Battery voltage too low
No display - If mains op.: power supply defective check/replace mains supply
or or wrong voltage/polarity
confused - System error
characters - Device defective
Err.1
Values exceeding measuring range
Electrode was disconnected
Sensor/cable defective
Err.2
Sensor/cable defective
Err.7
Fault in the device
Err.9
No sensor
and/or error in sensor
Er.11
Value could not be calculated
Error and System Messages During Oxygen Calibration
Display Description
Cal
Wrong temperature
Err.1
Cal
Wrong current: too low
Err.3
Cal
Wrong current: too high
Err.4
Cal
timeout: no stable measuring value
Err.6
Remedy
connect sensor
sensor defective -> return sensor to manufacturer for repair
replace battery
replace battery
replace mains supply, if error continues to exist: unit damaged
replace battery
disconnect battery or power supply, wait for a short time, reconnect
return to manufacturer for repair
check: are there any values exceeding the measuring
range specified? ->meas. value too high
Wait for final electrode signal being set
-> replace
-> replace
switch on again: if fault continues to exist, device is damaged
-> return to manufacturer for repair
connect suitable sensor
sensor defective -> return to manufacturer for repair
one of the measuring values required for calculation is missing
sensor missing or damaged (overflow/underflow)
Cause/Remedy
temperature has to be between 5 and 40°C
membrane dried up => store electrode in water for 2 hours
regenerate or replace electrode
check calibration environment (p.r.t.'How to calibrate oxygen electr.')
check calibration environment (p.r.t.'How to calibrate oxygen electr.')
air bubbles in the diaphragm head?
check calibration environment (p.r.t.'How to calibrate oxygen electr.')
