Resistance / continuity / diode / capacitance measurement
To make a resistance measurement, continuity test, diode test or
capacitance measurement, move the input shutter up to unlock the
input jacks.
Turn the rotary function switch to “Ω“. Now press the
MODE key to switch between resistance measurement, continuity
test, diode test and capacitance measurement. Now connect the
black test lead to the “COM“ jack and connect the red test lead to
the red jack.
9.1
Continuity test
When making a continuity test, an audible signal will sound as soon
as the resistance value is <50
Ω.
9.2
Diode test
To test diodes, connect the test leads to the diode now and
remember or write down the displayed reading. Now swap polarity
and compare the new reading to the first reading. The
measurement can be evaluated as follows:
If “OL“ is displayed after both measurements, the diode is defective.
If “OL“ is displayed after one measurement and typical values such
as 0.400
… 1.800 V are displayed after the second measurement,
this means that the diode works. If voltage readings are displayed
after both measurements, this means that the diode is defective. In
this case, the diode will cause a short circuit.
9.3
Capacitance measurement
A short time after connecting the test leads, a farad value will be
displayed. Note that the capacitors are charged during this
measurement. To avoid electric shocks, these should be
discharged after the measurement where needed.
9.4
Resistance measurement
The resistance reading will be displayed immediately when the test leads have been connected.
