→
if necessary, clean the probe and/or recalibrate the measurement sensor;
→
if necessary, check the process.
• The "warning" event may also be associated with one and/or other digital outputs. See section 8.10.23.
• A current of 22 mA may be emitted on one and/or other of the current outputs when an "error" event related
to either the monitoring of the fluid pH, redox, conductivity or temperature values or the monitoring of an
analogue input is generated. See section 8.10.22.
• See also section 9.3 If you encounter problems.
STATE : Choose to activate or deactivate monitoring of the impedance of the electrode selected.
This monitoring is done by the generation of a "warning" event if the impedance range defined in the "Warn Hi/
Lo" functions below is exceeded and an "error" event if the impedance range defined in the "Err Hi/Lo" functions
below is exceeded.
IMPEDANCE : Read the impedance, measured in real time, on the electrode selected.
TEMP. DEPEND. : Temperature coefficient of correction for the impedance measurement of a fluid. The default
coefficient is valid for probes sold by Bürkert
WARN. HIGH : Enter the impedance value above which a "warning" event is generated.
WARN. LOW : Enter the impedance value below which a "warning" event is generated.
ERR. HIGH : Enter the impedance value above which an "error" event is generated.
ERR. LOW : Enter the impedance value below which an "error" event is generated.
8.12.5 Monitoring the conductivity of the fluid
This function is used to monitor the fluid conductivity and define the device's behaviour if the ranges defined are
exceeded.
Refer to section 8.9 to access the "Diagnostics" menu.

A malfunction in your process or on the measurement cell may be revealed by too low or too high a fluid
conductivity.
To be warned when the conductivity is out of range:
→
activate monitoring of fluid conductivity in the "Status" function, and then
→
set a fluid conductivity range outside of which the 8619 generates a "warning" event and displays the icons
and .
