GDDO-20C AC / DC Electric Meter Calibration Ntaus
GDDO-20C AC / DC Electric Meter Calibration Device yog siv los txheeb xyuas qhov yuam kev ntawm ntau lub zog zaus hluav taws xob hauv cov tshuab hluav taws xob, suav nrog voltmeter, ammeter, wattmeter, ohmmeter, ib theem & peb theem AC lub zog ntsuas (yeem) thiab qhov yuam kev yooj yim ntawm DC volt-meter thiab ammeter.
Rau 'meter' ib feem, nws yuav siv high precision fais fab zaus AC collector raws li cov tub ntxhais technology, uas muaj xws li cov teeb liab processor (DSP) thiab 16-tus lej high speed analog-digital converter;Rau qhov chaw teeb liab, nws siv DSP thiab 16-tus lej siab ceev analog-digital converter los tsim cov teeb liab qhov chaw uas ua rau sine yoj teeb liab thiab distortion yoj teeb liab.
●Qhov tseeb chav kawm ntawm 0.05.Thaum ntsuas AC voltage, AC tam sim no thiab lub zog siv hluav taws xob, cov cuab yeej tau nruab nrog lub tshuab hloov hluav taws xob / zaus (DFC) nrog kev ua haujlwm zaus siab dua 60kHz thiab ntau qhov tam sim no, yog li qhov tseeb yog lav.
●Lub distortion nthwv dej ntawm 2 ~ 31 lub sij hawm, tus naj npawb, lub sij hawm thiab amplitude ntawm harmonics, thiab theem ntawm harmonic mus rau hauv paus nthwv dej yuav ua tau tag nrho cov programmed.
●6.5-nti xim TFT LCD npo, pom meej thiab ci.
●Nrog RS232 kev sib txuas lus chaw nres nkoj.
●Nrog lub peev xwm loj uas tsis muaj qhov tsis sib xws, tuaj yeem khaws cov txiaj ntsig ntawm 300 meters hauv kev sim, txhawb nqa cov ntaub ntawv saib thiab cov ntaub ntawv upload muaj nuj nqi.
●Nrog kev ntseeg tau zoo, yooj yim rau kev khiav lag luam.
