Calibrating the temperature sensor
The internal thermometer in the device is precisely calibrated upon delivery.
If you detect a possible temperature deviation when checking the thermal fluid using
a reference thermometer, the measurement values on the temperature sensor can be
adjusted.
For this purpose, the reference thermometer needs to be fitted to the flow line on the
device.
The factory calibration is overwritten when adjusted. Only use a
reference thermometer with a high level of precision for the calibration
process.
✓ The chiller is switched off and disconnected from the power grid.
✓ Allow the device and thermal fluid to warm up or cool down to room temperature.
➜ Attach a T-piece matching the inside hose diameter (Ø 8 mm) between the connection
for the pump flow line and your connection hose.
➜ Slide your reference thermometer into the still open end of the T-piece and attach the
thermometer.
✓ The calibrated reference thermometer has been installed in the flow line in a
process-capable manner.
