Remote Sensor Calibration
Figure C-6
Remote Sensor
Calibration Loop
This procedure requires a running chiller and a calibrated reference thermometer.
Note
If it is more convenient, perform the low-end calibration before doing the
high-end.
Do not pick calibration points that are outside the safe operating limits of the fluid
in your application. For example with water, 40°C and 5°C are typical high and low
calibration points.
Place the remote sensor and a calibrated reference thermometer in the high
temperature remote reservoir. Ensure the fluid temperature is stabilized.
Press the
key and the controller will display
rtd H
. Press
again and the
controller will flash between
rtd H
and the temperature.
Use the arrow keys to adjust the temperature to match the reference thermometer.
Press the
key again to accept the value.
Save calibration
Do not save calibration
Place the remote sensor and calibrated reference thermometer
in a low temperature reservoir. At the
rtd L
(low-end
calibration) display repeat the procedure.
After the low-end calibration is accepted
StorE
is displayed.
Press the up arrow to accept the calibration, press the down
arrow key to not accept it.
Note
After pressing the up arrow at the
StorE
prompt
wait several seconds before proceeding to ensure that a bad
calibration message (
Er 16
) does not appear. Premature use
of the keypad after pressing the up arrow may cancel the bad
calibration error message.
