 three phase LCD AC/DC voltage meter

Voltmeter is an instrument measuring voltage, common voltage meter - voltmeter Symbol: V, the galvanometer which has a permanent magnet, between the two terminals in series galvanometer a coil constituted by the wire coil placed in the magnetic field of the permanent magnet, and is connected via a transmission with a table of pointers. Most tables are divided into two vol-tage ranges. Voltmeter has three terminal, a negative terminal, two positive terminal, connected to the positive electrode and the positive voltage circuit of the table, a negative electrode connected to the circuit. Voltmeter must be connected in parallel with the test appliances. Voltmeter is a very large resistor, the ideal is that the open circuit voltage in parallel to the table in a parallel circuit (in parallel with other appliances) and appliances, if no other electrical appliances in the trunk, it is possible that the power measurement Voltage.
