Capacitance Measurements; Temperature Measurement; Frequency Measurement - Sonel CMP-2000 Manual De Uso

4. Touch probes to the diode. A forward-voltage drop is about 0.6 V
(typical for a silicon diode).
5. Reverse probes. If the diode is good, "OL" is displayed. If the di-
ode is shorted, "0.00" or another number is displayed.
6. If the diode is open, "OL" is displayed in both directions.
7. Audible Indication: Less than 0.03 V.

Capacitance measurements

1. Set the Function/Range switch to the "
2. Connect the red test lead to the "VΩ" jack and the black test lead
to the "COM" jack.
3. Discharge the capacitor before taking capacitance measure-
ments.
4. Touch the probes to the capacitor. Observe polarity when meas-
uring polarized capacitors.
5. Read the capacitance directly from the display.
6. The meter has a residual capacitance in the 6.6 nF and 660 nF
ranges, which is a normal status. Before taking measurements,
press the ZERO button to zero the residual capacitance.
7. When the capacitor to be tested is connected, if "dIS.C" symbol
indicates on LCD, it means there is voltage existing in the tested
capacitor and to be discharged before testing.
7.7

Temperature measurement

1. Set the Function/Range switch to the "Temp" position.
2. Remove leads and slide TEMP switch to the right to close lead
jacks.
3. Plug K-type thermocouple directly into the meter to measure
temperature.
4. Take temperature measurement using the thermocouple probe
and read the temperature from the display.
7.8

Frequency measurement

1. Set the Function/Range switch to the „Hz/%" position.
2. Connect the red test lead to the "VΩ" jack and the black test lead
to the "COM" jack.
3. Connect the test leads to the point of measurement and read the
frequency from the main display.
