A useful digital instrument designed to measure Joules and Watts in low voltage AC and DC circuits. The unit is powered from 240V.AC.mains but the circuits that it measures must be low voltage. Currents from 0.01mA to 10 amps can be handled and voltages up to 20V.DC. Or 15V.AC. Frequency from 50Hz up to 1kHz can be handled. Measures energy up to 999kJ and power up to 200W.
The simplest connection is for power source to be connected to the 2x Input sockets and the load is connected to the 2x Output sockets. The range is selected by button and the zero offset is by knob.
