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.
11.10 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 .
Press the “SELECT” button twice
to switch to diode test mode. The
diode symbol and “V” appear on
the display. Press the button again
to switch to the next 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). Con-
nect 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.
