Puas yog qib digital hluav taws xob muaj tseeb? Yuav ua li cas calibrate qib digital
1, Puas yog cov qib hluav taws xob digital yog qhov tseeb
Vim qhov nyuaj ntawm kev siv cov ntsuas qib ib txwm muaj thiab muaj peev xwm ua rau pom qhov tsis raug, qhov ntsuas qib digital tau tsim. Nws tuaj yeem tso saib cov ntawv nyeem ntawm lub vijtsam LCD, ua rau nws yooj yim heev. Txawm li cas los xij, qhov yooj yim ntawm kev siv lub ntsuas ntsuas qib yog qhov thib ob, thiab qhov tseem ceeb yog kom raug. Yog li, qhov ntsuas qib digital puas yog?
Qhov tseeb, qib digital tsuas yog ib txoj kev sib txawv, thiab nws cov ntsiab lus yog tib yam li qib tsis tu ncua. Qhov tseeb ntawm kev ntsuas tsis cuam tshuam, thiab qhov tseeb yog cuam tshuam nrog qhov tseeb ntawm qib digital.
Txawm li cas los xij, nws yuav tsum raug sau tseg tias tsis zoo li qib ib txwm muaj, qhov ntsuas qhov tseeb ntawm 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 thiab txias uas siab dhau lossis qis dhau tuaj yeem cuam tshuam nws qhov raug.
Yuav ua li cas calibrate qib digital
Cov txheej txheem handheld feem ntau yog calibrated siv tus qauv ntsuas. Nrog rau kev txhim kho thev naus laus zis, kev tsim cov qib digital ua rau kev ua haujlwm calibration ntawm qib yooj yim dua. Tsuas yog nias lub "calibration khawm". Hauv qab no, peb yuav qhia txog txoj kev ua haujlwm calibration ntawm qib digital:
1. Muab cov theem ntawm lub dav hlau tsis tshaj 3 degrees (uas tuaj yeem muab piv rau qib dab) 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 10 vib nas this, ces nias lub khawm calibration. Lub vijtsam zaub yuav tso tawm CAL2. Tom qab li 5 vib nas this, lub vijtsam LCD yuav tso tawm "Suc". Lub buzzer yuav beep peb zaug tsis tu ncua, qhia tias ua tiav calibration.
4. Yog hais tias lub LCD npo qhia peb dashes "---" tom qab calibration, nws qhia tau hais tias cov theem tsis sib npaug zos rau cov kab rov tav dav hlau thaum tig, thiab calibration tsis ua tiav. Kev ua haujlwm calibration tuaj yeem ua tau dua.
