Section 4 - Calibration and Maintenance
4.1 Calibration
Calibration allows the user to match the Controller’s bath temperature display to an external certified
reference thermometer. Calibration is performed as follows:
Set the desired operating fluid temperature set point and allow temperature to stabilize.
Press the P2 and P3 simultaneously and release and repeat until the display reads (oCx.x). Press
P1 and hold until (Cal) is displayed. This will take about 2 seconds.
At one second intervals, the displayed value will alternate between the actual bath fluid temperature
and the current offset value, which is the difference between the factory calibration setting and the
user’s reference temperature sensor. The maximum offset is
±0.9°C from factory calibration.
To change the calibration offset value, rotate the Select/Set Knob until the display matches the
reading on the reference temperature sensor. The display will continue to alternate between the
offset value and the calibrated display temperature.
Press the Select/Set Knob or the P1 Button to accept the entered value. When the new calibration is
stored and the mode is exited, (
) will appear on the display.
NOTE: The displayed offset value will also be accepted if there is no activity for 20 seconds.
4.2 Heater
The heater should be kept clean. If deposits build up on the heater, they may be removed by
scrubbing with a non-metallic (plastic) abrasive pad. Do not use steel wool.
