When the temperature value is less than the set limit, an error event is generated. Details about the error
event are given in chpt. 19.3.3.
When the temperature value is more than the set limit, an error event is generated. Details about the
error event are given in chpt. 19.3.4.

To enable the monitoring, i.e. to be informed when the temperature value of the water sample is outside
the normal range, enable the diagnostics. See chpt. 13.11.
10.6 Monitor the leakage-current value of the measuring
cell
The leakage current is the current that is required for the correct operation of the measuring cell. The value
of the leakage current is specific to each measuring cell and, thus, to each product. Upon delivery, the
product has a specific leakage-current value. Deterioration of the measuring cell causes the value of the
leakage current to increase. If the value of the leakage current reaches 4 times the initial value in absolute
value, then the measuring cell is out of order.
The parameter
ISFET leakage current makes it possible to monitor the leakage-current value. Do the fol-
lowing procedure:
1. Make sure that the login user level is
Installer . Refer to chpt. 9.4.
Do not configure and activate the low warning limit.
2. Configure and activate the high warning limit of the leakage-current value.

Select Warning triggers .
→ Select
High ISFET leak. current
and enter a leakage-current value, above which a warning event is gen-
erated. Validate with .

Select Activation flags . Select High ISFET leak. current . Validate with .
When the leakage-current value is more than the set limit, a warning event is generated. Details about
the warning event are given in chpt. 19.3.16.
