   Multi-function Three Phase Energy Meter Test Instrument(Integral Type) The RT***3B Multi-function Three Phase Energy Meter Test Instrument adopts internationally advanced new-generation digital power source technology, integrates all the technological advantages of both domestic and foreign watt-hour meter calibration software, and is introduced to global market by Rowwin Test in a powerful and sensational way. The Multi-function three phase energy meter test instrument’s power source uses MCU single chip microprocessor as its core technology and adopts various techniques as digital synthesis, digital frequency modulation, digital amplitude modulation, digital phase-shifting, pulse width modulation and so on to bring you such important features as high reliability and good load characteristics. Its more humane and intelligent meter calibration software makes it possible for an ordinary, heavy and boring calibration to be carried out more easily and efficiently.   Technical Parameters:   1.   Accuracy class: 0.1/0.*5 2.   Reference standard energy meter: Three phase wide-measurement range standard energy meter, Accuracy class:0.1/0.*5 3.   Output voltage: 3* *7.7/**0/**0/**0V Y/△,0~**0%Adjustment fineness:0.*1% full range, adjustable phase by phase 4.   Output current: 3* 0.1~**0A(**0A also available),0~**0%Adjustment fineness:0.***1A(minimum),adjustable phase by phase 5.   Phase shift:0~**0°Adjustment fineness:0.*1°,adjustable phase by phase 6.   Frequency:*5Hz~*5Hz,Adjustment fineness:0.*1Hz 7.   Output waveform distortion: Both voltage and current<0.5% 8.   Output voltage, current and power stability:<0.*5%(**0s) 9.   Output capacity(per phase):Current:**0VA(**0A); Voltage:**0VA(*6 meter testing positions)If necessary, the maximum load can be extended to Current:1,**0VA and Voltage:**0VA *0. Load characteristics: Resistive, inductive and capacitive(less than 4uF) *1. Harmonic wave output:***1st sub-harmonic wave, content<*0%;3rdControl of conduction angle(odd sub-harmonic wave);Control of wave group(sub-harmonic wave),5th and 7th sub-harmonic waves are superposed, content<*0% each; *2. Starting up current: Minimum 0.3 mA, Accuracy:5%,Starting power: Accuracy:5% *3. Tests: Demand test; Frequency impact test; Voltage impact test; Second pulse clock precision test; GPS clock synchronization; Constant calibration; Combined error test; Various register checking;RS**5 communication interface test *4. Energy meter testing positions:*6/*2(standard);3 to *0 meter testing positions also available *5. Testing functions: Accuracy testing, Creep testing(no load testing),Starting up testing, Harmonic testing, Repeatability testing, Influencing testing, Dial testing and etc *6. Power supply: AC 3***0/**0V±*0%,*0Hz(customer define);Max. power consumption:***0VA(*6 meter test positions)  Dimension: Split Type:Please contact us by rowwin.com *6 Meter testing positions(1 rack): ***0***0****0mm *2 Meter testing positions(2racks): ***0***0****0mm Cabinet:**0***0****0mm
