REL
REL mode takes the current main measurement as its reference. It is indicated
on the secondary display: REF.
•
The main display continues to indicate the instantaneous value measured
and the bargraph.
•
The secondary display ∆ indicates the absolute deviation between the
instantaneous value measured and the reference recorded.
•
The secondary display ∆ % indicates the relative deviation in % between the
instantaneous value measured and the reference recorded.
Range management may be "AUTOmatic" or "MANUal, depending on
the configuration when entering this mode.
The

% displays are managed in the same range.
In "AUTO" mode, they cannot fall below the reference range when the
REL mode was activated.
Example: Measurement of a 1.5 V

voltage with a reference set to 1 V:
Adjustment of the
reference
When the mode is active, a long press on the key opens a window for
setting the REF reference.
•
The key selects the digit to be modified.
•
The keys modify the digit selected.
•
The key can be used to exit from the menu after validating the new
reference.
