0.28″ 100V 10A Duel LED Voltmeter Ammeter BL+R VAM28

It is a dual digital Volt and Amp meter device that can measure current from 0 to 10A and voltage from 0 to 100V. It is a 0.28’’ device with 5 wires divided into 2 sets. Black and red are for the power supply and 3 wires to measure the voltage and current. So a digital voltage is a voltage that can be in only 1 of 2 states. The voltage can either be entirely off or LOW at 0V. Or the voltage can be entirely ON or HIGH at the peak voltage. Let’s say the voltage of the signal goes to 5V. This means the digital voltage can either be 5V or 0V.

The working of a digital voltmeter is converting an analogue signal into a train of pulses. The number of pulses is proportional to the input signal. Therefore, a digital voltmeter can be made by using any A/D conversion method. Initially, a voltage signal is introduced to the pulse generator.
