Circuit Continuity Test; Diode Test - Sonel CMP-1010 User Manual

5.8 Circuit continuity test

WARNING
Do not perform measurements on the circuit under the
voltage. Before the measurement disconnect the pow-
er and discharge capacitors.
To perform the continuity test:
 set the rotary switch at Ω
 press MODE/INRUSH button to display
 connect black test lead to COM terminal, and red test lead to
VΩHz%
 contact the tips of test probes to the points of measurement,
 read the measurement result on the display; the beep will be acti-
vated when resistance values are below approx. 50 Ω.

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
 press MODE/INRUSH button, to display
 connect black test lead to COM terminal, and red test lead to
VΩHz%
 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
