• It can be used to measure DC current, DC voltage, and can also be used as a galvanometer.
• The meter head is composed of a high-quality magnetic steel inner magnetic bracket, a yoke ring, a moving ring, a hairspring, a shaft tip seat and a bearing.
• When the current passes through the moving coil, a magnetic field is generated to interact with the magnetic field generated by the inner magnetic support and the yoke to generate a rotating torque and deflect the moving coil.
• When the rotating torque is balanced with the reaction torque produced by the hairspring, the pointer is in the balance position, indicating the measured value, and a mechanical zero adjustment knob is installed at the back of the meter.
• The instrument is a magneto-electric system structure, which is mainly composed of a meter head and a measuring circuit.
