Round models ranging in size from 2-1/2" to 4-1/2" are produced in either the ±2% of full scale AC repulsion or DC Moving Coil version. AC ranges are standard up to 50 amperes self contained and 600 AC volts. Ranges down 10 milliamperes AC are also standard. Both round and square models come in DC ranges from 20 microamperes to 50 millivolts to 750 volts DC. High current ammeter ranges with external shunt are available, as are special or non-standard ranges. The industrial meters shown here represent the many case styles and options in this series.
