D. Testing diodes (see figure 6)
Warning
To avoid damages to the Meter or to the devices under test, disconnect circuit power
and discharge all the high-voltage capacitors before testing diodes.
To test the diode out of a circuit, connect the Meter as follows:
1. Insert the red test lead into the terminal and the black test lead into the
COM terminal.
2. Set the rotary switch to and press SELECT button to select measurement
mode.
3. For forward voltage drop readings on any semiconductor component, place the red
test lead on the component's anode and place the black test lead on the component's
cathode.
Note:
● To remove the objects being tested from the circuit when measuring can obtain a
more accurate result.
● When diode testing has been completed, disconnect the connection between the
testing leads and the circuit under test and remove testing leads from the input termi-
nals.
