Yuav ua li cas xaiv ib qho kev ua tau zoo dua rangefinder cov lus qhia ntxaws:
1. Saib qhov ntsuas qhov tseeb: xaiv lub rangefinder nrog qhov tseeb ntawm ± 2 hli, uas tuaj yeem ua tau raws li cov qauv ntsuas ntsuas.
Rau qee qhov kev ntsuas engineering, suav nrog qhov kev ncua deb ntawm phab ntsa, kev teeb tsa ntawm cov ntaub thaiv, thiab lwm yam, tsuav yog qhov tseeb ntawm qhov ntsuas qhov ntsuas nyob hauv ± 2 hli, nws tuaj yeem ua tau raws li qhov ntsuas qhov deb.
2. Saib qhov ntsuas qhov deb: qhov kev xaiv qhov kev ntsuas qhov deb yog 50 meters.
Tam sim no feem ntau zoo dua me ntsis laser rangefinders muaj dual laser zog, uas tuaj yeem txhim kho qhov ntsuas qhov deb, thiab 50 meters tsis tuaj yeem ua tau raws li peb qhov kev ntsuas qhov deb, tab sis kuj ua tau raws li qhov kev ncua deb uas lub laser tuaj yeem ncav cuag.
3. Saib lub roj teeb lub neej: xaiv lub roj teeb qhuav thaum muaj xwm txheej ceev uas muaj ob qho tib si kev ua haujlwm ntawm kev them nyiaj ncaj qha thiab cov khoom siv hluav taws xob thaum muaj xwm txheej ceev, uas yog, nws muaj ob hom fais fab mov.
Yog tias lub roj teeb lub neej ntawm lub rangefinder tsis txaus, nws yuav tsis tsuas yog xav kom peb them ntau zaus, tab sis qee zaum, thaum siv rau lub sijhawm ntev, nws yuav tsis ua raws li peb cov kev cai siv txhua.
4. Saib cov khoom siv: feem ntau xaiv qhov sib xyaw ua ke ntawm cov kua nplaum sab nraud thiab cov khoom siv tawv tawv, xaiv cov khoom siv silicone rau cov nyees khawm, thiab tseem muaj kev ntsuas dej tsis zoo, tom qab ntawd koj tuaj yeem ua tiav qhov kev ua tau zoo ntawm cov dej tsis zoo thiab tiv thaiv lub caij nplooj zeeg.
Vim hais tias qhov dav dav finder siv nyob rau hauv qee qhov chaw nrog hnyav ib puag ncig, xaiv cov ntaub ntawv zoo dua tuaj yeem ua kom lub neej ntev ntawm cov khoom nrhiav ntau dua.
5. Saib ntawm lub vijtsam zaub: Xaiv lub vijtsam zaub, nws yuav tsum pom meej, thiab cov ntaub ntawv teeb tsa hauv lub vijtsam yuav tsum tsim nyog, txhawm rau pab txhawb peb kev nyeem ntawv.
Yog tias nws los nrog lub suab ua haujlwm, nws tuaj yeem muab lwm txheej pov hwm rau peb cov ntawv nyeem raug.
