6. del 9160 1pce Effective Value RMS Most alternating currents and voltages are expressed in effective values which are also referred to as RMS Root Mean Square values The effective value is the square root of the average of square of alternating current or voltage values Many clamp meters using a conventional rectifying circuit have RMS scales for AC measurement The scales are however actually calibrated in terms of the effective value of a sine wave though the clamp meter is responding to the average value The calibration is done with a conversion factor of 1 111 for sine wave which is found by dividing the effective value by the average value These instruments are therefore in error if the input voltage or current has some other shape than sine wave CF Crest Factor CF Crest Factor is found by dividing the peak value by the effective value Examples Sine wave CF 1 414 Square wave with a 1 9 duty ratio CF 3 Effective value Average value Conversion Reading Pror is Crest factor Waveform factor average sensing Vrms Vavg CF Vrms Vavg instrument 1 2 x 7 A f V2 x 2 2 0 v2 1 414 0 707 0 637 1 111 Ax1 11FA x100 A A 1 A 1 11 1 2 o 5Ax1 111 1 93 499 V3 A 0 5A 3 A v3 f 1 732 1 155 3 8 AvD 1 e D 1 111D A 1 AvD A A D N T x 100 AVD D 3 Other Function Data Hold Press the Data Hold Key to freeze the reading Pre
