Puas yog qib digital hluav taws xob muaj tseeb?
Vim qhov nyuaj ntawm kev saib cov thawj tswj hwm qib ib txwm muaj thiab muaj peev xwm ua rau pom qhov tsis raug, tus thawj tswj qib digital tau tsim. Nws tuaj yeem tso saib cov ntawv nyeem ntawm lub vijtsam kua siv lead ua kua, uas yooj yim heev. Txawm li cas los xij, qhov yooj yim ntawm kev siv tus pas ntsuas theem yog theem nrab, thiab qhov tseem ceeb yog qhov tseeb. Yog li, tus thawj tswj hwm qib digital puas yog?
Qhov tseeb, tus thawj tswj hwm qib digital tsuas yog muaj txoj hauv kev sib txawv, thiab nws txoj cai yog tib yam li tus thawj tswj hwm qib ib txwm muaj. Qhov tseeb ntawm qhov ntsuas yuav tsis cuam tshuam, thiab qhov tseeb yog cuam tshuam nrog qhov tseeb ntawm tus kav qib digital.
Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias tsis zoo li cov thawj tswj hwm qib zoo tib yam, kev ntsuas qhov tseeb ntawm cov thawj coj qib digital cuam tshuam los ntawm qhov kub thiab txias. Feem ntau, kev ntsuas yog qhov tseeb dua nyob rau thaj tsam ntawm 20-30 degree , thiab qhov kub siab lossis qis tuaj yeem cuam tshuam rau lawv qhov tseeb.
Yuav ua li cas calibrate tus kav qib digital
Cov thawj tswj hwm qib ib txwm muaj feem ntau calibrated siv tus qauv. Nrog rau txoj kev loj hlob ntawm thev naus laus zis, qhov kev tsim ntawm cov thawj coj qib digital tau ua rau kev ua haujlwm ntawm cov thawj coj qib yooj yim dua. Tsuas yog nias lub "calibration khawm". Hauv qab no yog ib qho kev qhia txog kev ua haujlwm calibration txoj kev ntawm cov tswj qib digital:
1. Muab tus ntsuj plig rau ntawm lub dav hlau uas tsis tshaj 3 degrees (uas tuaj yeem muab piv rau qib ntsuj plig) thiab tos 10 vib nas this.
2. Nias lub khawm calibration ib zaug, thiab lub vijtsam zaub yuav pom CAL1.
3. Tig cov qib digital los ntawm 180 degree, tos lwm 10 vib nas this, ces nias lub khawm calibration. Lub vijtsam zaub yuav qhia CAL2. Tom qab li 5 vib nas this, lub vijtsam LCD yuav qhia "Succ" buzzer beeping peb zaug tsis tu ncua, qhia txog kev ua tiav zoo.
4. Yog hais tias tom qab calibration, lub LCD npo qhia peb dashes "---", nws qhia tau hais tias tus pas ntsuas theem tsis sib npaug zos rau cov kab rov tav dav hlau thaum lub sij hawm tig, thiab calibration tsis ua tiav. Calibration tuaj yeem ua dua.
