Moving Iron A.C. Ammeters and Voltmeters
Designed to measure A.C. current or voltage, these meters indicate true r.m.s. values
and are substantially independent of system waveform. Scales are calibrated down
to 20%, and ammeters can have overload scales x2, x3, x5 or x6 for motor start duty.
Ammeters can be supplied for use with -/1A or -/5A current transformers, whilst
voltmeters can be scaled for use with voltage transformers. Heavy damping is
available as an option. Meters can be used to measure D.C. at reduced accuracy.
