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.
