PolyPower logs contain three-phase and single-phase AC and DC power data. Summary reports summarize the results of a test into brief tabular format. The user chooses what timeframe to summarize and what variables to list in the report. This type of report provides an excellent status record for systems and processes.

Comparison reports compare the data of two different segments of the same data log or two different data logs. Comparisons between logs typically present "before" versus "after" comparisons to prove savings if energy or cost. Comparisons between times within logs typically present peak load versus idle load comparisons. Since the user selects which variables to include in the report, the report can be quite extensive (70 variables such as voltage, current, power factor, watts, VA, VAR, cost, THD, frequency) for record keeping or quite minimal to increase the impact of the results.

Sellers of energy saving devices appreciate the ability to summarize before/after tests onto an 8-1/2 x 11 sheet with before and after energy use and cost. The difference between the before and after results are documented in both absolute and percentage terms. A claimed 15% savings in energy use per month could be documented and presented clearly to the decision-makers.
