6.2.2.1 Compensation of test leads resistance (Continuity, PE
conductor (PRCD))
This chapter describes how to compensate the test leads resistance in Continuity and
PE_conductor (PRCD) functions. Compensation can be carried out to eliminate the influence
of test leads resistance and the internal resistances of the instrument and adapters on the
measured resistance.
Connections for compensating the resistance of test leads

Compensation of test leads resistance procedure

Select the Continuity function

Set parameters (Output, Test current).

Connect test lead to the instrument between P/S and PE terminal on test socket ( Figure
6.21 ) or connect IEC test cable between IEC connector and test socket ( Figure 6.22 ).
Touch the key to compensate test lead / IEC test cable resistance.

Symbol is displayed if the compensation was carried out successfully.
