GENERAL DESCRIPTION

The phase rotation meter is constructed with epoxy encapsulated high voltage resistors, a
connecting cord, a ground lead and a meter display. The major elements are shown here:

The high voltage resistors limit the current through the connecting cord to a maximum
of about one milliamp. Although the connecting cord is insulated for voltage up to 10kV,
it should always be kept free and clear from you, ground and any other conductors.

WARNING:

The phase rotation meter has a range switch and requires add-on resistor

sticks for higher voltage ranges. Always completely remove the phase rotation meter from
the live circuit before changing the range switch position or adding or removing add-on
resistor sticks. Always use add-on resistor sticks in pairs, one on each stick.
