1 The meter head is a common design, i. e. the ground wire at the measuring end is interlinked with the ground wire at the power supply end (except the isolation meter). 2 The meter head is equipped with voltage calibration potentiometer, current calibration potentiometer, if there is any error, you can calibrate it, because the error is absolute. 3 The voltage meter adopts the design of automatic movement of the decimal point. 4 This meter has strong anti-interference ability and fast display refresh rate. 5 The meter head uses a wide power supply range: DC3.5 ~ 30V (except the isolation meter), the power supply reverse connection will not burn.
