The specific operation steps of the digital clamp meter
1. AC current measurement
①Turn the switch to the ACA1000A position.
②Keep the switch in a relaxed state.
③Press the trigger to open the jaws and clamp a wire. If there are more than two clamping wires, the measurement is invalid.
④Read the value. If the reading is less than 200A, turn the switch to ACA200A to improve accuracy. If you cannot read directly in a dark place due to environmental conditions, hold down the hold key and read in a bright place.
2. AC and DC voltage measurement
①When measuring DC voltage, turn the switch to ACA200A, when measuring AC voltage, turn the switch to ACV750V.
②Keep the switch in a relaxed state.
③Connect the red test lead to the "V/Ω" terminal, and the black test lead to the "COM" terminal.
④ The red and black test pens are connected in parallel with the circuit under test.
3. Resistance measurement
①Pull the switch to the appropriate range of resistance.
②Keep the switch in a relaxed state.
③Connect the red test lead to the "V/Ω" terminal, and the black test lead to the "COM" terminal.
④The red and black test pens are respectively connected to both ends of the resistance under test. It should be drained.
4. Switch test
①Turn the switch to 200n.
②The red and black test pens are respectively connected to the "V/Ω terminal COM" terminal.
③If the resistance between the red and black test leads is less than (50±25)Ω and the buzzer is turned on, the built-in buzzer will sound.

5. High resistance measurement
①Turn the switch to "EXTERNALUNlT" 20MΩ or 2000MΩ.
②The displayed value is unstable and is in a free state.
③ Insert the 3 plugs of the test accessories into the 3 input sockets of the clamp meter hole.
④The switch of the clamp meter and the range switch of the test accessories are placed in the 2000MΩ position.
⑤The input terminal of the test accessory is connected to the resistance under test;
⑥ Put the test accessory in the "ON" position, press the "PUSH" key, the indicator light will be on, and the display screen will display the measured value. If the reading is less than 19MΩ, the range of the clamp meter test accessory should be selected to be 20MΩ to improve accuracy.
