The PowerPad™ Model 3945 is a hand-held
three-phase power and power quality meter with a large easy-to-read
graphical color display. Measurements are displayed numerically and
graphically with coloured waveforms. The meter is menu driven with pop-up
functions that are activated at the push of a button. All necessary
measurements are available for a comprehensive power system check or
analysis.
The PowerPad Model 3945 with MN93 is supplied with a set of three
color-coded 240A current probes.
The PowerPad has a logging function, a transient capture function, an
event capture function, an optical RS-232 and an advanced software
(DataView® Professional), which can pilot the PowerPad and
provide comprehensive reports.
