Cov ntsuas hluav taws xob feem ntau siv hauv kev lag luam muaj peev xwm nyeem tau ntau tshaj ib hluav taws xob yam ntxwv. Cov feem ntau siv hluav taws xob ntsuas yog lub volt-ohm-milliammeter thiab lub clamp-on ammeter nrog lub peev xwm nyeem volts thiab ohms.
Hais txog qhov no, dab tsi yuav tsum tau xav txog thaum yuav ib lub ntsuas hluav taws xob?
tus nqi, raug, durability, yam ntxwv, thiab warranty.
Tsis tas li ntawd, lub tswv yim dab tsi yog siv nyob rau hauv lub ntsuas hluav taws xob los xam lub voj voog? Kev siv cov ntsuas digital Ohm lawd ntsuas thiab tso saib cov Circuit Court yam ntxwv. Qhov no tuaj yeem ua tau yooj yim vim tias tsuas muaj peb qhov sib txawv hauv Ohm txoj cai: Qhov twg yog qhov voltage, tam sim no, thiab tsis kam.
Tom qab ntawd, hom hluav taws xob sib txawv yog dab tsi?
Muaj plaub lub ntsiab hom hluav taws xob ntsuas : Flat-rate, ncua sij hawm, hnub ci thiab ntse meters . Hnub ci meters tseem muaj peb sub- hom : Net meters , ob-directional meters thiab dual metering. Cov meter koj muaj peev xwm cuam tshuam koj hluav taws xob tus nqi.
Dab tsi yog qhov tseeb ntawm feem ntau analogue?
Cov qhov tseeb tshaj plaws nyeem ntawv rau ib analog ' meter ' yog ib txoj hauj lwm pointer ntawm 2/3 ntawm tag nrho cov nplai thiab tag nrho cov nplai. Feem ntau, dc voltage ntsuas siv tag nrho suav muaj peev xwm ntawm ADC, txij li cov teeb liab txias yog ncaj nraim rau pem hauv ntej: nws siv cov kev faib tawm thiab cov ntxaij lim dej.

Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog kauj ruam transformers siv hauv kev xa hluav taws xob hluav taws xob?
Cov hluav taws xob hluav taws xob tau xa mus rau qhov ntev ntawm qhov hluav taws xob siab. Yog li, cov kauj ruam nce transformers yog siv ntawm cov chaw nres tsheb fais fab kom nce qhov hluav taws xob ntawm lub zog whereas cov kauj ruam-down transformers yog siv los txo qhov voltage mus txog 220 V
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
