描述:

Digital AC Voltmeter with LED Display RUICHI DMS-142 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 voltage measurement is Volt (V). The device has a high resistance. Voltmeters in an AC network. 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.
