Correct operation method of digital multimeter to measure voltage: -- AC current measurement method
1) Insert the black test lead into the COM jack. When measuring the current with the maximum value of 200mA, insert the red test lead into the mA jack. When measuring the current with the maximum value of 20A, insert the red test lead into the 20A jack.
2) Set the function switch to the AC current range A~ range, and connect the test leads to the circuit to be tested in series.
When the digital multimeter is in use, please refer to the DCA measurement of DC current and note 1, 2, and 3.
What is the meaning of the symbols in the multimeter:
(1) ~ indicates communication
(2) V－2.5KV 4000Ω/V means that the sensitivity is 4000Ω/V for AC voltage and 2.5KV DC voltage block
(3) A－V－Ω means measurable current, voltage and resistance
(4) 45-65-1000Hz means that the operating frequency range is below 1000 Hz, and the standard power frequency range is 45-65Hz
(5) 2000Ω/V DC means that the sensitivity of the DC gear is 2000Ω/V. The symbols on the clamp meter and the shaking dial are similar to the above symbols (others cannot be written all because the symbol format is not correct, indicating that the magnetoelectric system rectifier type has a mechanical reaction force meter. 'Indicates three-level anti-external magnetic field' means horizontal placement))).
