THE PRINCIPAL WORK? ABOUT? PMMC INST.
Operation of the device the PMMC is based on the principle that when a conductor in a magnetic field, a force on the conductor that is to move it to one side

Voltmeter?
VALU SERIES of Multiplayer is calculated as:-
The sensitivity of the analog voltmeter
Analog Voltmeter is mutual sensitivity full scale deflection current
The MAIN motion can be converted into an ammeter connected in parallel with the resistor connected is called a SHUNT
AMMETER
The shaft of the shunt is calculated as follows:-Rsh = IFSD x Rin
AC voltage, voltmeter
AC voltmeters are usually average response type and is calibrated in terms of existing values for a sinusoidal wave. Since most of the measurement voltage are sinusoidal signal so this method of measurement the effective value of alternating current with voltage works satisfactorily, and cheaper than a True RMS voltmeter responses. However, in the case of the measure of nonsinusoidal voltage signal, this device will read high or low depending on the form factor of the signal to be measured.
ANALOG multimeter
Analog multimeters, electrical measuring instruments used for measuring voltage, current, resistance, frequency and signal strength.
