Portable electronic instrument designed to obtain the best results by directly measuring active electrical quantities such as potential currents (voltages) or passive ones such as resistances, capacitances and others. It measures the apparent power of a system (voltage and current); parallel voltage and series current. Measurements can also be made for alternating currents and in various ranges. By placing the hook on the current cable it helps to measure amperes, it also includes two terminals that are placed on the phase and ground inputs to measure voltage. Together it helps to obtain the power (w) of the system.
