Good AC Volt-ammeter wiring (black version)

blue display ammeterIf I wanted to measure the voltage in the socket I bought this volt-ammeter. Measured voltage and current simultaneously. This is the biggest advantages

Measured voltage is 110V suitable for U.S. and also for the European Union 230
Its range is 80-300V. But not suitable for measuring the three-phase voltage. However, if you connect only one phase measurement device measures correctly. If you search for DC voltage use this DC voltmeter.

Current measurement without contact goes through the toroid sensor / transformer.Accuracy is good. I used to test the heater 230V 2000Watts Voltammeter measured 8.65 A. this useable acuracy

A wiring diagram is a simple two “power wire” i connect to phase and ground.After connect this two wires Voltammeter is turn on but measuring only voltage .If i will measuring current   i muss pass through the toroid one phase wire. After going phase wire  through the toroid i plug “load”.  Then voltammeter shows the volts and amperes.

Bee carefull 110V or 230 voltage can serious shocking  you body! If manipulating with wires turn off elektricity.Is good insured if the circuit fuse or circuit breaker
