REL key

Short press : Mode REL, the last value measured becomes the reference value derived
Long press : When in REL mode, a long press displays the reference being used. This

Pk +/- key

The fast positive or negative peak measurement functions (≥ 1 msec.) can be accessed by
repeatedly pressing this key in the V
functions.

Set the probes on the point to be measured. An audio signal indicates if the measurement
is stable. When you remove the probes, a second audible signal indicates that this stable
value displayed has been stored.

TECHNICAL SPECIFICATIONS

Only those values assigned tolerances or limits are guaranteed values. Values without
tolerances are given for information only (French standard NF C 42-670).
