2.4 General Operating Information
There are two principal Models in the 800 Series, the 800A and the 811A. The Model 800A
is used for power meter calibration and testing, whereas the Model 811A has the additional features
required for energy meter calibration and testing. The Models 800AE and 811AE are essentially
identical to their "A" counterparts with the exception that they have the ability to operate in an
enhanced accuracy mode.
WARNING
Before making any connections to the Series 800 Calibrator,
place it in the Standby state by pressing the Standby control.
This will ensure that there is no excitation at the voltage or
current terminals. If this procedure is not followed,
there is a possibility of shock from high voltage.
2.4.1 Model 800A/800AE
The following paragraphs describe the use of the Model 800A calibrator as a wattmeter calibrator.
