Measurement Instructions

AC Current (A~) Measurement

1. Open the jaws of the clamp meter and place them around the conductor carrying the current to be measured. ?️

2. Turn the rotary switch to the 'A~' position.

3. Insert the black test lead into the 'COM' jack and the red test lead into the 'A-' jack.

4. Read the measured current value on the display. Example: 5.68 A.

AC Voltage (V~) Measurement

1. Turn the rotary switch to the 'V~' position.

2. Insert the black test lead into the 'COM' jack and the red test lead into the 'V' jack.

3. Connect the other ends of the test leads to the AC voltage source. Ensure correct polarity: red lead to positive (+), black lead to negative (-).

4. Read the measured AC voltage on the display. Example: 220 V.

DC Voltage (V) Measurement

1. Turn the rotary switch to the 'V' position.

2. Insert the black test lead into the 'COM' jack and the red test lead into the 'V' jack.

3. Connect the other ends of the test leads to the DC voltage source. Ensure correct polarity: red lead to positive (+), black lead to negative (-).

4. Read the measured DC voltage on the display. Example: 12.57 V.

Resistance (Ω) Measurement

1. Turn the rotary switch to the 'Ω' position.

2. Insert the black test lead into the 'COM' jack and the red test lead into the 'V/Ω' jack.

3. Connect the test leads across the component or circuit to measure resistance. The device will beep for continuity if resistance is below approximately 100Ω. ?

4. Read the measured resistance on the display. Example: 500 Ω.

Frequency (Hz) Measurement

1. Turn the rotary switch to the 'Hz' position.

2. Insert the black test lead into the 'COM' jack and the red test lead into the 'V/Ω' jack.

3. Connect the test leads to the signal source for frequency measurement.

4. Read the measured frequency on the display. Example: 60 Hz.
