1. Ua kom meej tseeb tias qhov kev xav tau no yuav tsum yog AC los yog DC, thiab qhov ntsuas ntau npaum li cas tam sim no yuav raug ntsuas, vim hais tias qhov tseeb hluav taws xob muaj ntau yam kev hloov tam sim no. Li ntawd, tam sim no sensor yuav muab faib ua me me tam sim no thiab cov sensor loj tam sim no raws li qhov ntau ntawm tam sim no.
2. Kev muaj peev xwm tshaj qhov muaj peev xwm ntawm qhov sensor tam sim no;
3. Cov zis tawm yog dab tsi? Tam sim no lossis voltage? Piv txwv, tso zis hluav taws xob 4V;
4. Los txiav txim xyuas qhov tseeb ntawm tus sensor, qee leej yuav tsum tau muaj kev siab tshaj. Yog li, qhov tseeb yuav tsum tau kev nyaub siab thiab lub siab precision tam sim no yuav tsum raug xaiv.
5. Cov kev qhia ntawm lub hwj huam pab - AC teeb tam sim no, txhawm rau txheeb xyuas qhov hloov ntawm cov tswv yim tam sim no thiab tawm DC teeb liab linearly hloov nrog cov tswv yim tam sim no, feem ntau xav tau lub zog ua hauj lwm ntawm cov khoom tam sim no ntawm lub hwj chim pab khoom, xws li fais fab tuag voltage: + 15V;
6. Txiav txim siab rau qhov kub thiab txias;
7. Qhov zoo ntawm lub sensor yog ib qho tseem ceeb heev? Piv txwv li, kev txhim kho ntawm cov kev taw qhia los yog lub rooj tsav xwm, lub aperture yog ib puag ncig los yog square, tag nrho cov uas yuav tsum tau xav txog.
