The 5077 PowerCal is a precision test instrument designed to calibrate watt-meters, power meters, and kW-Hr meters.
The 5077 is controlled remotely from a standard PC via the RS232 (or USB) interface, or directly from Time Electronics 5051 Calibration System.
A user-friendly virtual front panel allows the four parameters to be set individually.
Frequency can be set in 0.1Hz steps from 45 to 400Hz, and phase in 0.1-degree steps. Alternatively power factor (PF) can be set in 0.01 steps.
The output can be displayed as VA or Watts.
