Amprobe Multitest-1000 Continuity-Tester - Manual (Page 14)

CABLES USED FOR THE TEST If the cables are changed or extended be sure and
recalibrate the instrument. During a continuity
test, if the resistance value free of calibration (that
is the resistance value less the calibration offset
value) is negative, the symbols
ν
as well as
blinking CAL are displayed (refer to 5 th screen
paragraph 4.1.3).
WARNING
Never disconnect the test leads while the word “Measuring” is being
displayed.

Measuring
To cancel the calibration parameters (and
the symbol CAL) it is necessary to perform a
calibration procedure with a resistance
greater than 5
Ω (for example with the test
leads disconnected). When a cancellation is
completed this screen is displayed first,
followed by the screen below:
