Alarms 1/2
Analog input alarms are used to monitor measured values
in relation to adjustable limit values.
The alarm settings for all analog device functions are explained together.

Calibration timers
Calibration timers prompt the user to calibrate sensors on a regular basis.
The settings for all analysis inputs and the universal inputs are explained to-
gether.

a
The entry field units depend on the configuration items "Electrode type" and
"Redox unit".
NOTE!
The following points must be observed for correct operation of glass electrode
monitoring via impedance measurement (see preceding table):
•
Impedance measurements are possible only with glass-based sensors.
•
Sensors must be connected directly to an analysis input for pH/Redox/NH
3
on the device.
•
Impedance converters must not be installed in the measuring circuit.
•
The maximum admissible cable length between sensor and device is 10 m.
•
Fluid resistances have a direct impact on the measurement result. It is
therefore advisable to activate the impedance measurement in liquids at a
minimum conductivity of approx. 100 µS/cm.
