Tus kheej -calibrating ib transformer tester yuav tsum tau cov cuab yeej txheem thiab kev txawj ntse. Nws suav nrog ua raws li cov txheej txheem calibration tshwj xeeb raws li cov qauv ntsuas. Cov neeg siv ib txwm tsis raug qhia kom sim qhov no lawv tus kheej. Yog hais tias tus kheej -calibration yog tsim nyog, thov mus saib cov nram qab no cov kauj ruam:
Paub meej tias tus kheej -calibration tau txais kev txhawb nqa. Feem ntau cov kws tshaj lij-qib xeem (xws li HDZRC series) yog lub Hoobkas- ntsuas thiab qhia meej meej, "Tsis txhob ntsuas koj tus kheej tshwj tsis yog muaj xwm txheej tshwj xeeb."
Yog tias lub cuab yeej muab cov ntawv qhia "calibration" lossis xav kom nkag mus rau tus qauv kev tiv thaiv tus nqi, txwv tus kheej -calibration tau txais kev txhawb nqa, tab sis tseem yuav tsum muaj cov cuab yeej ua haujlwm tshaj lij.
Npaj Standard Calibration Equipment
Tus kheej-calibration yuav tsum muaj qhov siab- tus qauv qhov tseeb; Txwv tsis pub, nws yuav tsis raug:
Standard Voltage / Tam sim no qhov chaw: tso zis qhov tseeb ib theem siab tshaj qhov ntsuas tau calibrated.
Standard Resistance Box: Qhov tseeb txog li 0.01%, xws li 10KΩ, 1KΩ, thiab lwm yam nruab nrab - range resistors.
Standard Turns Ratio Source: Siv rau kev simulating qhov sib piv cov zis ntawm tus lem ratio tester.
Tag nrho cov cuab yeej txheem yuav tsum nyob rau hauv nws lub sij hawm calibration siv tau.
Common Self-Calibration Types thiab Key Operating Points
DC Resistance Tester Tus Kheej -calibration
Txuas tus qauv resistor (piv txwv li, 10KΩ, 1KΩ), thiab calibrate rau xya ntau yam (20KΩ, 2KΩ, thiab lwm yam) raws li nyob rau ntawm - npo npo.
Yog hais tias lub kaw lus ceeb toom "Lub kaw lus tau kuaj pom qhov tsis raug ntawm cov resistor kev twb kev txuas," xyuas cov xaim lossis hloov tus qauv resistor.
Hloov Ratio Tester Calibration
Siv tus qauv hloov pauv piv cov teeb liab qhov chaw raws li cov tswv yim thiab sib piv cov ntsuas ntsuas nrog tus nqi tus qauv.
Kho qhov ntsuas sab hauv kom ntseeg tau tias qhov yuam kev tsawg dua qhov ntsuas qhov tseeb (piv txwv li, ± 0.1%).
Comprehensive parameter calibration (voltage, tam sim no, hwj chim)
Xa mus rau JJF (Tshiab) 58-2021 tus qauv, AC voltage (0.1 ~ 750)V thiab tam sim no (0.1 ~ 100)A yog ntsuas nyob rau hauv qhov ntau zaus ntawm 40 ~ 70Hz.
Qhov siab tshaj qhov yuam kev: Voltage ± 0.05%, Tam sim no ± 0.2% (clamp-on), Fais fab ± 0.5%
