DC Voltage Meters,
DC (Note 1)
AC (Note 2)
1. These DC meters require an external shunt from page C3, and an 8 to 10
2W wire-wound potentiometer (customer supplied).
2. These AC meters require use of a current transformer from page C5.
*External multipliers (Model 183) are furnished on 1-1/2” DC meters 500 volts or
higher; on 2-1/2” DC meters 750 volts or higher; and on 3-1/2” and 4 - 1/2” DC
meters 1000 volts or higher. All others have self-contained multipliers.
