Introducing the Model
933A
1.1 Scope
The Model 933A Portable Power Sentinel is designed to provide highly-
accurate measurement of electrical power quality and many other electrical
values important to the power industry. A true seven-channel instrument,
the Model 933A allows independent measurement of three-phase currents
and voltages (including neutral), and associated values.
Designed for data recording and storage, memory is divided between
two 128-MB flash cards. One memory card receives data at the highest
sampling rate directly from the DSP for waveform data storage, and
the other memory card stores the more accurate, standard data after
processing.
To enhance portable operation, the Model 933A has an internal Nickel
Metal Hydride (NiMH) battery. It also has a standard IEC-320 line power
inlet for normal operation and for battery charging.
While the 933A was designed to operate independently in portable
situations from the front panel, its capability is enhanced through using
Power Sentinal CSV 933  software. Hereafter, the application software is
referred to as “PSCSV”.
