Connect the sensor to pos. 1 on Controller and connect the power supply to pos. 8
on the Controller. See page 90.
Submerge the sensor into the pumped liquid. The pumped liquid and the air
temperature are to be +70 °F.
Note: It is important that the pumped liquid is stagnant as the calibration will be
misleading if the sensor is cooled by flowing water.
Press the buttons at pos. 6 and pos. 12 on the Controller for approximately
20 seconds.
When the green indicator lights at pos. 3 and pos. 9 on the Controller are constantly
on, release the buttons at pos. 6 and pos. 12.
All red indicator lights (except pos. 7) start flashing.
The calibration is completed.
