the calibration curve along with the selected
probe’s value in both °C and volts.
5. On the right side of the screen, the
Offset
field
allows for fine tuning of the calibration.
NOTE:
If an offset has been entered, the
original calibration curves will be shown as a
green line. The black line will move according
to the offset value entered in real time.
6. The
Perform Calibration
button starts the
guided calibration procedure: to perform a
calibration of a temperature probe it is
necessary to use a RTD/PT100 Simulator. The

KLA-DB-KIT Connectors and Cables.
