Puas yog qib digital hluav taws xob muaj tseeb
Ib qho yog cov qib hluav taws xob digital yog qhov tseeb
Nws yog ib qho teeb meem heev los siv lub ntsuas ntsuas ib txwm muaj, thiab tseem muaj qhov tsis raug ntawm qhov tsis raug thaum saib ntawm qhov muag liab qab. Yog li ntawd, lub ntsuas ntsuas qib digital tau tsim, uas tuaj yeem tso saib kev nyeem ntawv los ntawm cov kua siv lead ua kua tso zis, uas yooj yim heev. Txawm li cas los xij, qhov yooj yim ntawm kev siv lub ntsuas ntsuas yog theem nrab, thiab qhov tseem ceeb yog kom raug. Puas yog qhov ntsuas qib digital yog qhov tseeb?
Qhov tseeb, cov qib digital tsuas yog pom nyob rau hauv ib txoj kev sib txawv, thiab nws cov ntsiab lus yog tib yam li cov 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 tau muab sau tseg tias, tsis zoo li cov thawj tswj hwm qib zoo tib yam, kev ntsuas qhov tseeb ntawm cov tswj qib digital yog cuam tshuam los ntawm qhov kub thiab txias. Feem ntau, kev ntsuas yog qhov tseeb dua nyob rau thaj tsam ntawm 20-30 degree C, thiab qhov kub siab lossis qis tuaj yeem cuam tshuam nws qhov raug.
Yuav ua li cas calibrate cov zaub theem
Cov txheej txheem handheld feem ntau yog calibrated siv tus qauv ntaus ntawv. Nrog rau kev txhim kho thev naus laus zis, kev tsim kho qib digital ua rau kev ntsuas qib yooj yim dua,
Tsuas yog nias lub "calibration khawm" los qhia txoj kev ua haujlwm calibration ntawm tus kav qib digital:
1. Muab tus pas ntsuas theem rau ntawm lub dav hlau tsis tshaj 3 degree (uas tuaj yeem muab piv rau qib) thiab tos 10 vib nas this.
2. Nias lub khawm calibration ib zaug, thiab lub vijtsam zaub yuav tso tawm CAL1.
3. Tig lub ntsuas qib digital 180 degree, tos 10 vib nas this, thiab tom qab ntawd nias lub khawm calibration. Cov zaub yuav tso tawm CAL2. Tom qab li 5 vib nas this, lub LCD npo yuav tso saib "Succ" thiab lub buzzer yuav beep peb zaug tsis tu ncua, qhia tau hais tias ua tau zoo calibration.
4. Yog hais tias tom qab calibration, lub LCD zaub screen qhia peb dashes - - - ", qhia tias kab rov tav kab rov tav tsis sib npaug zos rau lub dav hlau kab rov tav thaum lub sij hawm tig thiab calibration tsis ua tiav, lub calibration lag luam tuaj yeem rov ua dua.
Nco tseg: Thaum siv tus yuam sij calibration los ntsuas cov qib digital, tus qauv 0 degree tsuas tuaj yeem rov pib dua ntawm lub dav hlau tsawg dua 3 degree. Yog hais tias lub dav hlau siab tshaj 3 degree, calibration key yuav tsis ua hauj lwm.
