Kunshan voltmeter manufacturer

Voltmeter is a kind of instrument to measure voltage, commonly used voltmeter - voltmeter. Symbol: V, there is a permanent magnet in the sensitive galvanometer. A coil composed of wires is connected in series between the two terminals of the galvanometer. The coil is placed in the magnetic field of the permanent magnet and connected with the pointer of the meter through the transmission device. Most voltmeters are divided into two ranges. The voltmeter has three terminals, one negative terminal and two positive terminals. The positive pole of the voltmeter is connected with the positive pole of the circuit, and the negative pole is connected with the negative pole of the circuit. The voltmeter must be connected in parallel with the appliance under test. The voltmeter is a fairly large resistor, ideally considered open circuit. The range of voltmeter commonly used in junior high school laboratory is 0 ~ 3V and 0 ~ 15V.
