Frequency Measurement; Measurement % Of Duty Cycle (Pulse Filling Indicator); Measurement Of Resistance - Sonel CMP-3000 Manual De Uso

5.4 Frequency measurement

To perform frequency measurement:
 set the rotary switch at Hz%,
 connect black test lead to COM terminal, and red test lead to
VΩ Hz%CAPTemp terminal,
 contact the tips of test probes to the points of measurement,
 read the measurement result on the display.
See also sec. 6.3.2.

5.5 Measurement % of duty cycle (pulse filling indicator)

To perform the measurement:
 set the rotary switch at Hz%,
 press MODE button, until symbol % is shown on the display,
 connect black test lead to COM terminal, and red test lead to
VΩ Hz%CAPTemp terminal,
 contact the tips of test probes to the points of measurement,
 read the measurement result on the display.

5.6 Measurement of resistance

WARNING
Do not perform measurements on the circuit under the
voltage. Before the measurement disconnect the pow-
er and discharge capacitors.
To perform measurement of resistance:
 set the rotary switch at Ω
 connect black test lead to COM terminal, and red test lead to
VΩ Hz%CAPTemp terminal,
 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.
