Description
Product introduction:
Night vision DC ammeter, voltmeter Q96-ZC-G is a meter used to measure the strength of a current in a DC circuit. When it is necessary to measure a large current, a low resistance with a certain resistance value can be connected in parallel at the two input terminals to expand the range. The zero point of its scale is usually placed at the extreme left of the scale.
In the magnetoelectric measuring mechanism, because the wire of the movable coil is very thin, and the current also needs to pass through the hairspring, the current allowed to pass is very small, about several microamperes to several hundred microamperes, so its practical value is very small. . According to the principle that the parallel circuit has a shunt effect, in practice to measure a large current, a shunt resistor must be added. Therefore, the DC ammeter is usually composed of a magnetoelectric measuring mechanism and a shunt resistor in parallel. Because the magnetoelectric ammeter can only measure DC current, it is also called DC ammeter.
