Diode test
Ensure that all circuit elements, circuits and components to be measured and other test
objects are completely switched off and discharged. Otherwise, the multimeter could be
damaged.
 Connect the black test lead to the COM jack [5] and the red test lead to the V/Ω jack [6].
 Set the range selector switch [4] to the
position in the Ω measuring range.
 Connect the red test probe [7] to the anode and the black test probe [7] to the cathode of
the diode to be tested.
 The forward voltage is indicated in volts on the display [1]. If "1" is displayed on the display
[1], the diode is measured in the reverse biased-direction or the diode is defective. Perform
an opposite pole measurement for check purposes.
HOLD function
A measured value on the display [1] can be saved by pressing the HOLD button [3]. Press the
HOLD button [3] again to return to the measuring mode.
