Voltmeter is meters with a moving iron are intended for measurement of AC voltage of frequencies from 15 Hz to 100 Hz. They measure rms values independently on the signal form of current or voltage. The scale is interchangeable. The accuracy class is 1.5. The meter can be direct connection for a small rating or from voltage transformer connection.
