Setting the Offset Calibration

This sub-menu allows you to match the Circulator’s temperature display to an external reference
thermometer. A value from -3.0° to +3.0°C may be entered; the factory default is 0.0°C.

IMPORTANT:

To prevent the Offset Calibration value from being changed unintentionally, the following

power down/power up sequence is required to enable the Offset Calibration function.

1. Turn Mains power OFF by disconnecting the electrical cord from the outlet.

2.

Turn Mains power ON while pressing and holding the

key.

3.

When STANDBY appears on the display, release the

key and press

.

You can now

proceed as outlined below.

The Offset Calibration function will remain enabled until the electrical power is turned OFF by pressing
the

key.

To Access:

Press the

key until OFFSET CALIBRATE appears on the display.

To Change:

Press

or

.

To Accept:

Press

or allow the LCD to return to the main operational display

(approximately 10 seconds).

CAUTION:

The Offset Calibration value is always shown in degrees C, even if degrees F is selected as

the temperature unit in which the control and actual bath temperatures are displayed. Your Immersion
Circulator will automatically convert the °C offset calibration value to the correct °F display offset value.
