Trouble-shooting

9
9.1
The transmitter constantly monitors its functions itself. If an error occurs which the device
recognises, this is indicated on the display. The error number is under the unit display of the
main measured value. If more than one error occurs, you can call these up with the MINUS key.
Refer to the "System error messages" table for the possible error numbers and remedial
measures.
Should a malfunction occur without any transmitter error message, please refer to the
"Process-specific errors" or the "Device-specific errors" tables to localise and rectify the error.
These tables provide you with additional information on any spare parts required.
9.2
You can display and select the error messages with the MINUS key.

Tests and/or remedial measures
1. Switch device off and then on again.
2. Load device software compatible with the
hardware (with optoscope, see
"Optoscope service tool" section).
3. Load measurement-parameter specific
device software.
4. If the error persists, send in the device for
repair to your local supplier or replace the
device.
Invalid configuration. Repeat download, check
optoscope.
Load software compatible with hardware
Load measurement-parameter specific device
software.
Check glass electrode for glass breakage or
hair-line cracks;
Inspect electrode plug-in head for moisture
and dry if necessary;
Check medium temperature.
Replace ISFET.
Check temperature sensor and connections;
check device and measuring cable with
temperature simulator if necessary.
Check correct option selected in field A5.
Check reference electrode for contamination
and damage; clean electrode.
Repeat calibration and renew buffer solution;
replace electrode if necessary, check device
and measuring cable with simulator.
