Variant in Analog Meter: AC Amp Meter | AC Volt Meter
Analogue panel meters, has moulded polycarbonate cases are suitable for the measurement of AC currents and voltage. Analogue meters indicate rms-values error of indication may occur for extreme waveforms (e.g. phase gating controls) & for frequencies above 100 KHz. This have wide range of application an all kinds of panel board (control distributes AMF, APFC instrument panel).
