5.4.3 Compensation of test leads resistance
This chapter describes how to compensate the test leads resistance in both continuity functions,
R LOWΩ and CONTINUITY. Compensation is required to eliminate the influence of test leads
resistance and the internal resistances of the instrument on the measured resistance. The lead
compensation is therefore a very important feature to obtain correct result.
symbol is displayed if the compensation was carried out successfully.

Compensation of test leads resistance procedure
 Select R LOWΩ or CONTINUITY function.
 Connect test cable to the instrument and short the test leads together (see
 Figure 5.16).
 Press the TEST key to perform resistance measurement.
 Press the CAL key to compensate leads resistance.

Note:
 The highest value for lead compensation is 5 . If the resistance is higher the
compensation value is set back to default value.
