描述:

The digital AC voltmeter with LED display RUICHI DMS-145 is a measuring instrument for reading the level of electrical voltage. It is connected in parallel to the load or directly to the voltage source (U). The unit of measurement of voltage is Volt (V). The meter has a high resistance. Voltmeters in AC networks. The operation of such devices consists in converting the variable voltage value into a constant one. After that, the signal is amplified and sent to the measuring mechanism of magneto-electric action.
