Note:

Release voltage of the input terminals is about <3.5V.

5-5-2 Testing Diode

1) Application

The quality of diodes is tested.

2) How to use

Connect the plug of black test lead to COM measuring input
terminal and plug of red test lead to measuring terminal.
Set the function switch to ' / ' and select ' ' by pressing
the SELECT switch.
Apply the black test pins to the cathode of the diode and the
red test pin to the anode.

Check reading for judgment of good or defective.

A zero reading indicates a shorted diode (defective).
An OL indicates an open diode (defective).

Apply the red test pins to the cathode of the diode and the
black test pin to the anode

The display shows OL, if diode is good. Any other
readings indicated the diode is resistive or shorted
(defective).

After measurement, release the red and black test pins from
the object measured.
