1. Lub tshuab hluav taws xobcrane nplaiqhib tsis tau. Ua ntej lub tshuab hluav taws xob cranenplaiyog kho, thov kom paub tseeb tias lub tshuab hluav taws xob crane nplai tsis tshwm sim los ntawm cov teeb meem ntawm lub fuse, hloov hluav taws xob, hluav taws xob thiab hluav taws xob hloov. Xyuas seb lub tshuab hluav taws xob crane scale transformer puas muaj AC110/220 input thiab AC18V tso zis. Thov tshem lub roj teeb thiab qhib lub AC fais fab mov kom paub seb lub roj teeb voltage tsis txaus. (Kev ntsuas lub roj teeb voltage, nws yuav tsum siab tshaj 6V, thov them yog tias nws qis dua 5.5V, thiab thov hloov lub roj teeb thaum nws them tag nrho thiab khiav tawm sai sai).
2. Cov zaub ntawm cov hluav taws xob crane nplai tsis zoo. Txuas lub LCD pins ntawm ib txwm hluav taws xob crane nplai nyob rau hauv parallel nrog lub LCD ntawm kho hluav taws xob crane nplai los ntawm txhais tes, thiab tom qab ntawd tig lub tshuab saib seb lub LCD ntawm lub crane ib txwm muaj qhov tsis zoo. Yog tias tsis yog, koj tuaj yeem txiav txim siab tias tsis muaj teeb meem nrog LCD ntawm lub tshuab hluav taws xob crane. Xyuas seb CPU pins ntawm lub tshuab hluav taws xob crane yog oxidized, txias welded los yog luv luv. Seb tus pins thiab qhov ntawm lub LCD yog oxidized, txias welded los yog luv luv-circuited. Xyuas seb kab ntawm CPU thiab LCD puas qhib.
3. Lub ntsuas hluav taws xob crane tsis rov qab mus rau xoom txhawm rau xyuas seb qhov tso zis hluav taws xob tus nqi ntawm cov khoom thauj khoom puas nyob hauv tus qauv. Yog tias nws tsis suav nrog tus qauv, thov xa mus rau qhov thib kaum rau kev them nyiaj. Yog tias nws tsis tuaj yeem them rov qab, thov xyuas seb lub sensor puas muaj teeb meem. Thov ua raws li cov lus qhia hauv phau ntawv qhia txog kev kho qhov hnyav.
4. Lub tshuab hluav taws xob crane tsis pub ntsuas qhov hnyav. Saib xyuas seb tus nqi ntawm cov khoom siv hauv crane puas ruaj khov, txawm tias muaj kev sib txhuam hauv ntau qhov chaw ntawm lub xov tooj ntawm tes, seb qhov kev tswj fais fab puas ruaj khov, seb lub op amp Circuit Court yog qhov qub, thiab seb lub rooj tsav xwm ntawm A / D Circuit Court muaj txawv teb chaws teeb meem, txawm hais tias lub tswv yim resistor / capacitor / lim capacitor puas lawm los yog leaks. Xyuas seb qhov tso zis hluav taws xob tus nqi ntawm lub tshuab hluav taws xob crane nplai sensor puas nyob hauv tus qauv. Yog tias nws tsis suav nrog tus qauv, thov xa mus rau qhov thib kaum rau kev them nyiaj. Siv qhov hnyav los ntsuas seb plaub taw ntawm lub lauj kaub uas hnyav npaum li cas. Thov ua raws li cov lus qhia hauv phau ntawv qhia ua qhov hnyav calibration ntawm hluav taws xob crane nplai.
5. Lub teeb liab ntawm lub ntsuas ntsuas crane yog qhov qub, thiab cov zaub yog 0kg. Yog tsis muaj qhov hnyav, xyuas seb lo lus tsis zoo tshwm nyob rau sab laug sab sauv ntawm qhov ntsuas ntsuas qhov hnyav. Yog tias qhov tshwm sim no tshwm sim, rov pib dua tom qab kaw. Xyuas seb tus nqi teev los ntawm kev faib tus nqi puas ua raws li lub teb chaws tus qauv. Lub ntsiablub hom phiajyog tias lub sensor yog nyob rau hauv kev sib cuag nrog ADF txuas plug. Xyuas seb cov kab hluav taws xob puas yog qhib Circuit Court, thiab siv lub rooj tshawb nrhiavmuaj peev xwm ntes. Tshawb xyuas seb lub tonnage ntawm qhov ntsuas puas yog raws li qhov tseeb tonnage. Unplug lub roj teeb ntawm lub cev nplai, tshem tawm cov kav hlau txais xov ntsuas, ntsaws lub roj teeb ntawm lub ntsuas lub cev, thiab siv cov chaw taws teeb tswj los hloov lub tshuab kom pom tias nws ua haujlwm. Tom qab cov kauj ruam thib rau ua tiav, koj tuaj yeem hloov kho cov channel yog tias daim tshev zoo li qub.
6. Lub ntsuas ntsuas crane tuaj yeem tso saib qhov hnyav hnyav, tab sis nws tsis tuaj yeem luam daim ntawv los xyuas seb qhov hnyav npaum li cas yog tshaj 99 phaus. Yog tias nws dhau, nws tsis tuaj yeem luam tawm. Nias cov zaub-tag nrho meej-paub meej kom rho tawm. Yog tias lub tshuab luam ntawv tsis ua haujlwm, xyuas seb qhov kev sib txuas puas raug txiav lossis soldered, txwv tsis pub hloov lossis kho. Yog tias lub khawm luam ntawv puas lawm, yog tias tsis muaj suab thiab tsis muaj lus teb tom qab nias, cov keyboard puas thiab yuav tsum tau hloov. Ribbon upside down. Lub meter roj teeb yog tsawg.
7. Lwm yam kev daws teeb meem ntawm crane nplai Lub ntsuas ntsuas tsis tuaj yeem raug them. Yog tias qhov kev sib txuas rau lub charger tsis cuam tshuam (uas yog, tsis muaj qhov hluav taws xob tso rau ntawm lub qhov rais ntawm lub charger), nws yuav yog qhov ntsuas qhov ntsuas qhov ntsuas tau tshaj tawm (qhov hluav taws xob qis dua 1V), thiab lub charger. Yog tias nws tsis tuaj yeem kuaj pom, koj tuaj yeem nias thiab tuav lub charger tawm khawm ua ntej ntsaws rau hauv lub ntsuas. Tsis muaj lub teeb liab hnyav tom qab lub ntsuas ntsuas tau qhib, thov xyuas seb lub roj teeb hluav taws xob ntawm lub ntsuas lub cev puas zoo li qub, ntsaws rau hauv lub kav hlau txais xov transmitter, thiab tig lub zog ntawm lub transmitter. Yog tias tsis muaj teeb liab, thov xyuas seb cov channel ntawm lub ntsuas puas sib haum rau lub transmitter.
