The 5077 PowerCal is a precision test instrument
designed to calibrate watt-meters, power meters, and kW-Hr meters.
PowerCal 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 0.1 Hz steps
from 40 to 400Hz, and phase as degrees or power factor (PF).
The output can be displayed as VA or power, and can be switched
on and off from the panel. An additional operation is required
prior to the selection of high voltages for safety reasons. |
