TRMS digital wattmeter
  DIGIWATT is a digital multimeter with floating inputs simultaneously displaying the 3 electric values: voltage, current and power. DIGIWATT measures the TRMS effective values of the U I W measurements, possibly with direct component superimposed. The wide bandwidth of the apparatus allows measurements to be made from DC to 70kHz or on chopped signals (frequency converters, industrial choppers, rectified supplies ..
