Specification of Volt Meter OTTO 500V
Voltmeter is an instrument that serves to measure the voltage. With the multiplier plus tool will improve the ability of the measurement instrument voltmeter many times.
The magnetic force will arise from the interaction between magnetic fields and strong currents. The magnetic style will be able to make the needle gauge voltmeter to move when there is no electricity. The greater the electrical current mengelir the greater the deviation needle occurs.
