PA2553 User Manual pdf


The six-key front panel has four "soft" keys with menus that simplify the selection of measurements.  In addition to numerical results, the PA2553 captures waveforms with 200-point precision.  These waveforms  can be displayed or directly output at full resolution to a PCL printer.  Power and amplitude measurements with a base accuracy of 0.1% are automatically synchronized to the fundamental frequency.  Peak measurements of voltage, current and power include continuous, inrush and history modes plus an accumulation mode for W-Hr, A-Hr and VA-Hr.
