In this example, the measured object is
copper and will be corrected to 25 Degrees
Celsius based on the measured
(temperature probe) temperature.
The correction formula:

Tk
234.5 for copper
225.0 for aluminium ( aluminium may be as high as 240)
Alternative: Correction with "

When temperature correction is activated
the following screen will appear.
To deactivate the temperature correction go
to the Temp Menu.
Use the rotary knob, turn clockwise or
counter-clockwise to select NoCorr.
By pressing the rotary knob, the setting is
confirmed.
