Moving Iron AC Ammeters and Voltmeters Designed to measure ac current or voltage, these meters indicate true RMS values and are substantially independent of system waveform. Scales are calibrated down to 20%, and ammeters can have overload scales of x2, x3, x5 or x6 for motor start duty. Ammeters can be supplied for use with -/I A 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 dc at reduced accuracy. Ammeters: 0.5-100A ac direct connected (40A for Maximum system voltage...
