MATECH MS2208 Harmonic Power Clamp Meter Tester Multimeter Trms Voltage Current Power Phase Angle Test 1.The meter can be used for testing power, voltage, current, peak value, phase, frequency, power factor, phase angle, and reaction factor, etc. of single-/three-phase circuit; automatic phase sequence testing is possible for 3-phase measurement. 2.True effective value measurement: accurate measurement is possible even with serious distortion in current waveform. 3.Low-consumption high-speed single-chip microprocessor is employed and sophisticated algorithm is applied, as a result, results can be obtained rapidly and precisely, and up to 20 harmonics and distortion value thereof can be measured. Hand-held, clamp-type structure, with light weight, convenient for carry-on.
