Description
The PowerPad 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 to 830Vrms; 6500Arms with a complete family of clamp-on and flexible 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.
Memory Info
The 4MB of memory is conveniently partitioned to let you store four different types of data, synchronized or independent of each other. You can store up to 12 screen snapshots or up to 50 captured transients. Capture transients down to 1/256th of a cycle. Detect peak voltage or current. See transformer K-factor display, power factor display, phase imbalance and harmonic distortion.
