Cov chav kawm raug ntawm cov ntsuas hluav taws xob yog hais txog cov chav ntsuas ntsuas uas ua tau raws li cov qauv ntsuas ntsuas thiab ua kom ntsuas qhov yuam kev hauv qhov txwv. Nws kuj yog ib qho tseem ceeb qhia txog hluav taws xob ntsuas qhov ua tau zoo.
Tam sim no, muaj plaub qhov tseeb ntawm cov ntsuas hluav taws xob uas nquag siv: 2.0, 1.0, 0.5S thiab 0.2S, uas feem ntau qhia los ntawm A, B, C thiab D hauv Europe.
| Chav kawm raug | Kev ntsuas yuam kev |
| 2.0 | ± 2 feem pua |
| 1.0 | ± 1 feem pua |
| 0.5,0.5S | ± 0.5 feem pua |
| 0.2,0.2S | ± 0.2 feem pua |
Ntawm lawv, chav kawm raug ntawm cov ntsuas hluav taws xob siv los ntawm cov neeg siv khoom hauv tsev tsis tsawg dua 2.0.
Chav Kawm 1.0 'meter' yog siv dav tshaj plaws, feem ntau yog siv rau tsev neeg thiab kev lag luam thiab kev lag luam hluav taws xob ntsuas. Kev lag luam uas xav tau qhov tseeb siab yuav xaiv cov metres saum cov chav kawm 0.5S. Ntau lub tuam txhab tsim cov chav kawm 1.0 ' meter ' raws li qhov ntsuas yooj yim.
Chav kawm {{0}}.5S meters muaj qhov raug siab dua li chav kawm 1.0. Nws yog tsuas yog siv rau kev ntsuas hluav taws xob hauv kev lag luam thiab cov chaw siv hluav taws xob me me, vim tias muaj qhov xav tau hluav taws xob loj thiab ntau qhov kev xav tau ntse, xws li kev ntsuas ntau lub sijhawm, ob txoj kev siv hluav taws xob metering, thiab lwm yam.
Chav kawm 0.2S meters yog siv rau hauv chaw nres tsheb fais fab. Ntxiv nrog rau nws tus kheej kev siv hluav taws xob, cov chaw nres tsheb fais fab feem ntau xa hluav taws xob mus rau sab nraud, uas yuav tsum muaj kev xav tau siab. Yog li ntawd, multi-functional ntse meters thiab rooj vag meters tau tshwm sim kom tau raws li qhov xav tau.
Qhov 's' nyob rau hauv chav ntsuas hluav taws xob qhov tseeb yog dab tsi {{0}}.2s & 0.5s txhais li cas? Qhov sib txawv tseem ceeb ntawm lawv yog qhov sib txawv qhov yuav tsum tau ua rau lub teeb load metering.
Cov ntsuas tsis-S-chav kawm tsis muaj qhov yuam kev hauv qab 5 feem pua Ib (rated tam sim no), thaum S-chav kawm meters muaj qhov yuav tsum tau ua yuam kev ntawm 1 feem pua Ib, uas txhim kho cov metering yam ntxwv ntawm lub meter nyob rau hauv lub teeb load. Thaum lub teeb loads, S-chav kawm muaj qhov ntsuas qhov tseeb dua li cov tsis-S-chav kawm. TOPSCOMM tuaj yeem kho cov ntsuas hluav taws xob ntse nrog cov chav kawm sib txawv raws li cov neeg siv khoom xav tau, txais tos los tham.
