Yuav ua li cas xaiv lub laser nrug meter
Thaum xaiv qhov rangefinder, ntau lub ntsiab lus los xav txog:
1. Kev ntsuas ntau
2. Kev ntsuas qhov tseeb
3. Lub sijhawm siv
Nws tuaj yeem muab faib ua cov xwm txheej hauv qab no:
a) Kev ntsuas qhov deb tsuas yog yuav tsum tau ua nyob rau hauv thaj tsam ntawm ob peb meters lossis kaum ob meters,
Nyob rau hauv rooj plaub uas qhov kev xav tau raug tsis siab. Cov lus qhia - "Ultrasonic rangefinder" tuaj yeem xaiv.
Lus Cim - Kev ntsuas cov txiaj ntsig ntawm ultrasonic rangefinders cuam tshuam rau ib puag ncig, thiab lawv cov kev ruaj ntseg thiab kev taw qhia tsis zoo dua li cov laser rangefinders. Txawm li cas los xij, lawv kuj pheej yig thiab tsim nyog rau kev ntsuas sab hauv tsev.
b) Kev ntsuas qhov deb tsis ntev thiab feem ntau yog siv sab hauv tsev, nrog rau qhov yuav tsum tau muaj qhov tseeb.
Cov lus pom zoo - Koj tuaj yeem xaiv yuav ib lub handheld laser rangefinder raws li qhia hauv daim duab sab laug.
Lus Cim - Handheld laser rangefinders yog qhov tsim nyog rau kev siv sab hauv tsev, nrog rau kev ntsuas qhov tseeb thiab ua tau zoo. Thaum ntsuas sab nraum zoov, qhov tseeb ntawm cov khoom siv ntawm tes laser rangefinders txo qis vim muaj kev cuam tshuam ntawm cov teeb meem sab nraum zoov.
(Yog hais tias cov neeg siv yuav tsum tau ua kom pom nyob rau hauv ib puag ncig sab nraum zoov, nws raug nquahu kom muab cov kws tshaj lij laser pom thiab cov reflectors ua ke kom ua tiav qhov kev ntsuas qhov xav tau thiab cov txiaj ntsig.)
Ceeb Toom: Cov khoom siv hluav taws xob txuas ntxiv siv los ntawm lub laser rangefinder muaj cov xim liab spectral pom, uas yuav ua rau qhov muag tsis pom kev puas tsuaj thaum saib ncaj qha.
c) Qhov ntsuas qhov deb yog qhov ntev thiab feem ntau yog siv rau sab nraum zoov.
