ACV LOZ Low impedance

Low impedance input: False voltage generated by large capacitive equipment can be measured.
The input impedance of a low-impedance multimeter is 300kΩ. It can discharge the residual voltage and determine whether the residual voltage exists.
The input impedance of an ordinary multimeter is as high as 10MΩ. Therefore, residual voltage cannot be identified, resulting in misjudgment or security risks.
There will be residual voltage after powering off large capacitive equipment.
Applied to all electrical equipment, such as reactive power compensation cabinets, large commercial fluorescent lamps.
