.Introduction
ETCR7300 Series Large CaliberThree PhasePowerTester is well
designedandmanufactured for measuring three phaseAC voltage,current,
leakage current, phasebetween currentand voltage, phasebetween phase
voltage,frequency, power energy, phasesequence,activepower, reactive
power, apparentpower, power. It isamultifunctional, digital,intelligent tester.
