This series was designed to meet industrial requirements and for other applications where rugged metal or
phenolic cases with glass fronts provide long service under adverse conditions. 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 and on the following pages represent the many case styles and options in
this series. For exact specifications and certified dimensions, please contact the factory
