Measurement Of Resistance - Sonel CMM-11 Manual De Uso

Do not measure the voltage when an electric motor located
within the circuit is being switched on or off. Resulting volt-
age spikes may damage the meter.
To perform DC voltage measurement:
 set the rotary switch at
 connect black test lead to COM terminal, and red test lead to
VΩHz%
 contact the tips of test probes to the points of measurement; red
probe should be applied to the point of higher potential,
 read the measurement result on the display.

Measurement of resistance

Do not perform measurements on the circuit under the volt-
age. Before the measurement disconnect the power and dis-
charge capacitors.
To perform the resistance 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 Ω on the screen,
 contact the tips of test probes to the points of measurement; the
best solution is to disconnect one side of the tested element, to
prevent the remaining part of the circuit interfere with the read-out
of the resistance value,
 read the measurement result on the display.
