When taking a resistance measurement, make sure that the points that come
into contact with the probe tips are free from dirt, oil, solder and other impuri-
ties. These substances may distort the result.
The "REL" button only works when a measurement is displayed. It cannot be
used when "OL" is displayed.
11.9 Diode test
Make sure that all objects that you wish to measure (including cir-
cuit components, circuits and component parts) are disconnected
and discharged.
Turn the multimeter on and select
the measurement mode
Insert the red test lead into the Ω
measurement socket, the black
test lead into the COM measure-
ment socket.
Check the measuring leads for
continuity by connecting both
measuring probes to one another.
A value of approx. 0.000 V should
be shown.
Connect the two test probes to the
object that you want to measure
(diode). Connect the red test lead
to the anode (+) and the black test
lead to the cathode (-).
The continuity voltage ("UF") will be shown in Volts (V). "OL" indicates that the
diode is reverse-biased (UR) or defective (interrupted). Try taking the measure-
ment again with the opposite polarity.
After measuring, remove the test leads from the measured object and turn the
multimeter off.
