5.9 Diode test

WARNING
Do not perform measurements on the circuit under the
voltage. Before the measurement disconnect the pow-
er and discharge capacitors. Do not test the diode un-
der voltage.
To perform the diode test:
 set the rotary switch at Ω
 connect black test lead to COM terminal, and red test lead to
VΩLoZV
 press MODE button, to display V
 contact the tips of test probes to the diode. The red test probe
should contact the anode and the black should contact cathode,
 read the test result on the display – the forward voltage is dis-
played.
 For a typical silicon rectifier diode, it is approx. 0.7 V, and for
a germanium diode it is approx. 0.3 V
 For LEDs with a low power, typical voltage value is in the
range of 1.2...5.0 V depending on the colour.
 If the diode is polarized in the reverse direction, or there is a
break in the circuit, the display will show OL.
 When the diode is shorted, the meter will show a value near 0 V,
 after completing the measurements, remove test leads from the
terminals of the meter.
