Features:The 3-phase clamp-type digital power meter is a hand-held intelligent harmonic power tester, with both functions of digital current testing and power testing. The tester is comprised of three channels including voltage, current, and power as well as a micro single chip system, and it is equipped with a powerful software for measurement and data processing functionsIt can measure, calculate, and display voltage, current, active power, power factor, apparent power, passive power, frequency, harmonic parameters, with stable performance and operation convenience. The meter is especially suitable for the measurement and examination of on-site power equipment and power-supplying circuits;With hand-held clamp structure, small volume, and light weight, it can be easily carried by the user, which makes it easy and fast for doing measurement.With PC RS232 interface and for windows graphics software.Automatic shutdown, automatic ranging, data holdBacklight display, undervoltage indication, true RMS measurement, 6000 count displaySpecifications:Brand:PEAKMETERJaw opening size: R50mmData storage: 100 groupsDisplay: 6000 countInterface:Rs232 AC voltage: 0.1 ~ 600 v(1.2% + 5)AC current: 0.1-1000 + / - (2.0% + 5)Active power: 0.1kW~600kW (3.0%+5)Apparent power: 0.1 kva ~ 600 kva(3.0% + 5)Reactive power: 0.1kVAr~600kVAr (4.0%+5)Power factor: 0.3 ~ 1(2.0% + 2)Harmonic Measurement: 45Hz~65Hz Harmonic NO.1 (3.0%+10) Harmonic NO.2-6 (3.5%+10) Harmonic NO.7-8 (4.5%+10) Harmonic NO.9-10 (5.0%+10) Harmonic NO.11-15 (7.0%+10) Harmonic NO.16-20 (10%+10) Power supply: 4 x1.5v AA battery(Not included)Safety category: CE cat.III 600V RoHSPackage size: Approx. 32.5*22*6.5cm/12.8*8.66*2.56inWeight: 1379gPackage includes:1 * MS2205 Clamp Meter (batteryNot included)1 * Test Probe 3 * Test Clip 1 * Rs232 Interface Cable 1 * Portable bag1 * StrapNote:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering..
