ZERO ADJUSMENT (REL)

The zero adjustment (or measurement lead compensation) function serves to
quantify the influence of the measurement leads and deduct it from the

The results of the zero adjustment will then be taken as the measurement zero
(origin).

measurement contact tips as shown
opposite
- press the REL key: R is then displayed and
the resistance and voltage values are set to
zero
- the connections to the battery to be tested
can now be carried out.
Warning :
The lead compensation applies only to the
measurement range selected beforehand
and only until the instrument is switched off.
