Error and System Messages During Oxygen Calibration
Display
Description
Cause/Remedy
Cal
Wrong temperature
temperature has to be between 5 and 40°C
Err.1
Cal
Wrong atmospheric pressure
atmospheric pressure has to be between 500 and 1100 hPa
Err.2
Cal
Wrong current: too low
membrane dried up => store electrode in water for 2 hours
Err.3
regenerate or replace electrode
check calibration environment (p.r.t.'How to calibrate oxygen electr.')
Cal
Wrong current: too high
check calibration environment (p.r.t.'How to calibrate oxygen electr.')
Err.4
air bubbles in the diaphragm head?
- Battery voltage too low
replace battery
No display
- If mains op.: power supply defective check/replace mains supply
or
or wrong voltage/polarity
confused
- System error
disconnect battery or power supply, wait for a short time, reconnect
characters
- Device defective
return to manufacturer for repair
Battery voltage low
replace battery
In case of mains op.: wrong voltage
replace mains supply, if error continues to exist: unit damaged
Err.2
Sensor/cable defective
-> replace
Err.1
Values exceeding measuring range
check: are there any values exceeding the measuring
range specified? ->meas. value too high
Electrode was disconnected
Wait for final electrode signal being set
Sensor/cable defective
-> replace
Err.9
No sensor
connect suitable sensor
and/or error in sensor
sensor defective -> return to manufacturer for repair
Er.11
Value could not be calculated
one of the measuring values required for calculation is missing
sensor missing or damaged (overflow/underflow)
Err.7
Fault in the device
switch on again: if fault continues to exist, device is damaged
-> return to manufacturer for repair
Cal
Second calibration point is not
check calibration environment (p.r.t.'How to calibrate oxygen electr.')
Err.5
within the allowable range
air bubbles in diaphragm head?
electrode needs maintenance or has to replaced
Cal
timeout: no stable measuring value
check calibration environment (p.r.t.'How to calibrate oxygen electr.')
Err.6
