Measurement Of Capacitance; Current Measurement - Sonel CMM-11 Manual De Uso

 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.

Measurement of capacitance

Risk of electric shock. Disconnect the power supply from the
tested capacitor and discharge all capacitors before any
starting capacity measurements.
To perform the measurement:
 set the rotary switch at Ω
 connect black test lead to COM terminal, and red test lead to
VΩHz%
 press MODE button, to display nF on the screen,
 contact the probe tips to the tested capacitor,
 read the measurement result on the display.

Current measurement

To avoid the electric shock, the device must not be connect-
ed to circuits in which the measuring voltage exceeds 600 V.
