The AVO / Multi-Amp PAM-275R Digital Phase Angle Meter was designed specifically for electrical system applications. It is a battery-operated or line-powered instrument. Incorporating two identical isolated input circuits, the unit permit precision measurements to be made of the phase angle relationship between two currents, two voltages or a voltage or a voltage and a current.

The PAM-275R is commonly used in testing and calibrating protective relays, phasing out circuits, checking differential relay schemes, checking polyphase watthour and varhour meter installations and verifying the polarity of CTs and PTs.
