Features & Applications:
The PowerPad® Model 3945-B 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 colored 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-B with MN93 is supplied with a set of three color-coded 240A current probes. In addition, it has a logging function, a transient capture function, an event capture function, an optical RS-232 and an advanced software (DataView®), which can pilot the PowerPad® and provide comprehensive reports.
