Temperature Compensation
Background
1. Select the
Temperature
Compensation
mode
If the resistance of a DUT at a particular temperature is
needed, the compensation function can be used. This
function can simulate the resistance of a DUT at a
desired temperature. If the ambient temperature and the
temperature coefficient of the DUT are known, it is
possible to determine the resistance of a DUT at any
temperature.
The Temperature Compensation works on the following
formula:
