Temperature compensation 
For obtaining the insulation resistance under a temperature other than current ambient temperature. 
Converts the measured value of resistance to the insulation resistance under a reference ,temperature,.and display the result. 
Depending on the different properties of test objects, there are 10 modes of compensation.
