Entering a Calibration Offset
This menu item allows you to offset all bath temperature readings by -7
to +7ºC. For example, if the Calibration Offset is set to +0.5º the bath will
display temperature readings of 20ºC, 50ºC and 70ºC as 20.5ºC, 50.5ºC
and 70.5ºC, respectively.
The Calibration Offset is always set in ºC. If you have selected ºF as
the temperature unit, the Water Bath automatically converts the ºC
calibration offset value to the correct ºF value when normal operation is
resumed.
To prevent the Calibration Offset from being changed unintentionally,
the following power down/power up sequence is required to enable the
Calibration Offset function:

value. As the Calibration Offset value is entered, the reading on the
upper display will also change to reflect the new calibration offset
