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.
LOW  05.06.01 Message >99.9

instrument detected a
resistance
higher
than 5

therefore it
will proceed with
