DATA COMMUNICATION
This procedure permits to recall some important values recorded during
the measuring & calibration phases of the controller. These values are
reset after each new calibration!
1.
Press
SET
.
2.
Press
¿
or
À
until the display shows [diAGn] and press
CAL
to
continue or
SET
to cancel.
3.
The display shows the cell constant of the conductivity cell connected
to channel-1, e.g. [cc1=1.056]. Press
CAL
to continue or
SET
to
cancel.
4.
The display shows the cell constant of the conductivity cell connected
to channel-2, e.g. [cc1=0.981]. Press
CAL
to continue or
SET
to
cancel.
5.
The display shows the lowest value ever measured by channel-1, e.g.
[Mi=635]. Press
CAL
to continue or
SET
to cancel.
6.
The display shows the highest value ever measured by channel-1,
e.g. [MA=807]. Press
CAL
to continue or
SET
to cancel.
7.
The display shows the lowest value ever measured by channel-2, e.g.
[Mi=312]. Press
CAL
to continue or
SET
to cancel.
8.
The display shows the highest value ever measured by channel-2,
e.g. [MA=381]. Press
CAL
to continue or
SET
to cancel.
1.
Select the desired °C channel with
¿
or
À
and press
CAL
.
2.
Measure the real °C value of processed liquid with an other electrode
and meter.
3.
Press
¿
or
À
until the display shows [ShiFt] and press
CAL
to start
the automatic calibration procedure.
4.
The display shows e.g. [°C=22.3]. Calibrate to the proper value with
¿
or
À
and press
CAL
to return to the measurements. Press
SET
here if you wish to return to the original readings. The display shows
[rESEt?]. Press
CAL
to reset the shifted values or press
SET
to
cancel.
∗
When the selected channel has been programmed to control °C, it
cannot be calibrated unless a Pt1000 (or Pt100) is connected to the
proper input.
∗
Without Pt1000 (or Pt100), change the manual temperature
compensation with
¿
or
À
and press
CAL
to return to the
measurements.

Two recorders, one for each channel, can be connected to the (+) and (-)
terminals (OUT1) and (OUT2). The 4 to 20 mA output range corresponds
with the pre-set values (see 'Recorder' page 5).
