5.3 CALIBRATION
The controller should be calibrated regularly, to reach a high security in the measurement. The
instrument is pre-set for calibration at 5
%
.
During the calibration, the latest output signal is "frozen", the relays are open and all regulation is
interrupted.
See appendix "Calibration instruction" for calibration.
5.4 OPERATION
Measuring is started when the power supply is turned on. After an interruption of the measuring, it can
be restarted by pressing
=
when the EXIT TO MEASURE diode is activated.
The display shows the actual measured value in the solution measured at the same time as the
corresponding mA-signal is sent to the output.
During the operation, the diode at
MEASURE is activated. If a relay is closed the corresponding diode
activates.

Alarm Diode ALARM
5.5 ALARM
When the measured value has exceeded the pre-set limit values during a period longer than the pre-
set time delay, the alarm relay is activated and the diode at alarm is lit up. If the function "shutdown at
alarm" is activated (on) the regulation stops, otherwise it continues.
The alarm shuts down either when the measured value is within the limit values or when measuring is
interrupted by pressing
+
and
-
at the same time.
