Resistance Measurements; Continuity Measurements; Diode Tests - Sonel CMP-2000 Manual De Uso

1. Set the Function/Range switch to the A~/A
2. Press the trigger to open the transformer jaws and clamp them
around a conductor. Jaws should be completely closed before tak-
ing a reading.
3. The most accurate reading will be obtained by keeping the con-
ductor across center of the transformer jaws.
4. The reading will be indicated on the main display.
5. Reduce the range setting if set too high until a satisfactory best
resolution reading is obtained.

Resistance measurements

1. Set the Function/Range switch to the "Ω" position.
2. Turn off power to the circuit under test. External Voltage across
the components causes invalid reading
3. Connect the red test lead to the "VΩ" jack and the black test lead
to the „COM" jack.
4. Connect the test leads to the points of measurements and read
the value from the display.
7.4

Continuity measurements

1. Set the Function/Range switch to the
Ω/
/ , to select the continuity test.
2. Turn off power to the circuit under test. External Voltage across
the components causes invalid reading.
3. Connect the red test lead to the "VΩ" jack and the black test lead
to the „COM" jack.
4. Connect the test leads to the two points at which continuity is to
be tested. The buzzer will sound if the resistance is less than ap-
proximately 30 Ω.

Diode tests

1. Set the Function/Range switch to the
Ω/
/ button twice to select the diode test.
2. Turn off power to the circuit under test. External voltage across
the components causes invalid readings.
3. Connect the red test lead to the "VΩ" jack and the black test lead
to the „COM" jack.
