F peak factor waveform peak RMS value Crest Factor 6 waveform peak RMS value When checking the measurable crest factor of our power measuring instruments please refer to the following equation Crest factor CF measuring rangeXCF setting 3 or 6 measured value RMS However the peak value of the measured signal must be less than or equal to the continuous maximum allowed input The crest factor on a power meter is specified by how many times peak input value is allowed relative to rated input value Even if some measured signals exist whose crest factors are larger than the specifications of the instrument the crest factor standard at the rated input you can measure signals having crest factors larger than the specifications by setting a measurement range that is large relative to the measured signal For example even if you set CF 3 CF 5 or higher measurements are possible as long as the measured value RMS is 60 or less than the measuring range Also for a setting of CF 3 measurements of CF 300 are possible with the minimum effective input 1 of measuring range Calculation Method of Voltage and Current and Procedure to Set Synchronous Source AC signals are repeatedly changing waveforms in terms of instantaneous values An averaging calculation by the repeated periods is required to be performed to measure the power value of the AC signals The WT1800 uses an ASSP method to perform averaging
