TEST LEADS
Before each measurement always assure that the
calibration is for the cables in use. During a
continuity test, if the resistance value free of
calibration (that is the resistance value less the
calibration offset value) is negative, the symbol
is displayed. Probably the calibration resistance
value stored in the instrument memory is not for
the cables in use, therefore a new calibration must
be performed.
6.1.1.1. Procedure to reset test leads calibration parameters
To cancel calibration
parameters
it
is
necessary to perform a
calibration procedure
with a resistance of
test leads higher than
5
(for example with
open test leads). When
a cancellation is effected
the screen to the right
is displayed temporarily.
