The JL-101 single phase electric meter and the JL-103 three phase electric meter can real-time measure
and display the electric parameters of electric circuits such as current,
voltage frequency, power (active power, reactive power, apparent power), power factor,
four-puadrant electrical energy and so on in AC circuit.
It can be mainly used in any low-voltage experiments such as basic AC circuit,
motor, AC power distribution, new energy technology and ets.
