    GF211B Multi-function Double Clamp Digital Phase Current-voltage Meter

    Product Description
    GF211B Multi-function Double Clamp Digital Phase Current-voltage Meter Application Applicable to relay protection, electric power measure, electric power construction and conversion engineering and other professional, is the electric power department, factories and mines, the petroleum chemical industry, the metallurgy system for the secondary circuit check ideal electric meters. GF211B multi-function double clamp digital phase current-voltage meter is a multifunctional measurement, touch-tone phones operation, to switch range, the measured data storage, keep, measuring array with communication software, but through the instrument interface upload data storage, and realize the large capacity can be output print report or phase diagram of the double clamp digital phase current-voltage meter. GF211B very suimeter for electricity measurement, electricity check, electric power substation maintenance, inspection and relay protection, differential detection, start experiment field use. And for all the power colleges as wiring discriminant training tools and teaching equipment. GF211B multi-function double clamp digital phase current-voltage meter is A full digital, many parameters measurement instrument power frequency, instrument to apply advanced computer technology, using the high performance A/D converter to direct exchange sampling method is realized power parameters measurement of frequency thanked the [voltage RMS (U1, U2), current RMS (I1, I2), phase (Ø U1U2, Ø I1I2, Ø U1I1, Ø U2I2, Ø U1I2, Ø U2I1), active power (P), reactive power (Q), work rate (F), frequent power factor (PF)]. Instrument circuit structure is simple, less parts, high reliability, built-in high-performance lithium ion rechargeable batteries without external power supply can work. Host, accessories of integration of the pormeter packaging, easy to carry. Products in the power supply management, inspection and measuring equipment maintenance of power is widely used, is the electric power system measurement, biotech, electricity each branch such as one of the necessary instruments. Main Features The 65 X50 LCD display, high brightness backlighting, show intuitional clear. Automatic detection range, direct measurement and display true RMS voltage, current, voltage and voltage, and that the voltage and current, current and all kinds of current phase relationship, real-time measuring active power, reactive power, frequency and power factor. Built-in rechargeable lithium battery power instrument, shut off the backlight can work continuously 18 hours, open when backlit can for eight hours or more. Current plain amplitude and phase characteristics, can be in 5 mA-10 A range accurate measurement phase. Double channel, symmetrical design, mutual insulation, safe, reliable, and can detect the discriminant transformer of wiring group, the U-U phase value, two voltage input circuit insulation isolation, won't cause measured short circuit and burned instrument. With pointed mouth clamp ampere current transformer, clamp the tip, high accuracy, strong anti-jamming ability, in the line of dense applications particularly convenient. Instrument built-in ten thousand clock chip can accurately record test time, for reference. The built-in memory, can save 60 group measurement data, but through the panel direct function keys access has saved data set. With USB conversion interface, will the meter measuring data group uploaded to the PC and form to print report archive, also can be equipped with micro printer site print directly output. The instrument is simple to use, easy to operate very applicable to the electric power colleges as wiring discriminant training tools and teaching equipment. Super small streamlined structure, handheld, small volume, light weight.
