Resistance measurement
4
To measure the resistance, turn the rotary
switch to position „ ". Then connect
the measuring contacts to the object to
be tested. The measured value acquired
appears on the display. If „O.L." appears
on the display instead of a measured
value, either the measuring range has
been exceeded or the measuring circuit
is not closed or has been interrupted. Re-
sistances can only be measured correctly
in isolation; therefore, the components
might need to be disconnected from the
remainder of the circuit.
When measuring resistance, to avoid the risk of the results
!
of a measurement being distorted, there must be no traces of
dirt, oil, solder spray or other contamination on the test prods.
Continuity test
5
To test continuity, turn the rotary switch
to position „ " and press the „Mode"
switch twice to activate the „Continuity
test" function. Then connect the
measuring contacts to the object to be
tested. A measured value of < 150 ohms is
recognised as continuity; this is con rmed
by an audible signal. If „O.L." appears on
the display instead of a measured value,
either the measuring range has been
exceeded or the measuring circuit is not
closed or has been interrupted.
