Built by Power Professionals, For Power Professionals

The Model 928A Power System Multimeter with Floating-Point DSP^TM Digital Signal Analysis is an AC Power measurement instrument, providing outstanding performance and flexibility in a small, hand-held package. Not only does the Model 928A measure basic data and power quantities, but it also measures power quality including harmonics, flicker, sags, surges and interruptions. Incorporating a graphic LCD display, serial communications, real time clock and an unprecedented combination of features makes the Model 928A the ideal instrument for the power professional.

Features
The Model 928A includes a bright, 128 x 64 graphic LCD display, a 30-key multifunction backlit keypad, and an isolated serial interface. The Model 928A may be powered either from four AA type cells (alkaline or NiMH) or an optional external, +7 Vdc plug-in power supply.

Inputs
The Model 928A uses two identical input measurement channels capable of measuring either voltage or current. The dual inputs allow for voltage to current, voltage to voltage or current to current measurements with a basic accuracy of 0.1%. The flexible current inputs are compatible with both voltage output and current output CTs. Convenient current transformer calibration tables help eliminate errors introduced by the CTs and lessen their effect on system measurements. A special 0 to 40 mA range allows for accurate low level (< 10 mA) measurements.

Accessories
The Model 928A requires an external CT for current measurements, such as the AP0001300 (1000:1) or the AP0009800 (100:1). Optional accessories include a tilt/bail handle, soft case, test leads, external +7 Vdc power supply, and other CTs.
