Frequency Measurement; Measurement % Of Duty Cycle (Pulse Filling Indicator); Dc Voltage Measurement - Sonel CMM-11 Manual De Uso

5.2

Frequency measurement

To perform frequency measurement:
 set the rotary switch at
 press MODE button, until symbol Hz is shown on the 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.
5.3 Measurement % of duty cycle (pulse
filling indicator)
To perform the measurement:
 set the rotary switch at
 press MODE button, until symbol % is shown on the 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.
5.4

DC voltage measurement

Electric shock hazard. The ends of measuring probes, due to
their length, may not reach the live parts inside some net-
work connections of low-voltage electrical equipment, be-
cause the contacts are arranged inside the sockets. In such
a case, the read-out will be 0 V with the simultaneous pres-
ence of voltage in the socket.
Before acknowledging the absence of voltage in the socket
make sure that the ends of the of the probe touch the metal
contacts inside the socket.
