Kev ceev faj tshwj xeeb rau kev siv lub multimeter
1. "Mechanical zero adjustment" before use
Mechanical zero adjustment hais txog kev kho lub taub hau hairspring yam tsis muaj lub hwj chim rau, kom lub pointer taw tes rau xoom.
Ua ntej siv lub multimeter, koj yuav tsum xub saib seb lub pointer ntawm lub multimeter yog raws nraim nrog rau sab laug xoom scale kab.
2. Thaum lub sij hawm siv, nws yog nruj me ntsis txwv tsis pub kov cov hlau ib feem ntawm lub xeem cwj mem nrog koj txhais tes
Txhawm rau siv lub multimeter, koj yuav tsum siv cov ntawv xeem rau kev sib txuas. Nws yog nruj me ntsis txwv tsis pub kov cov hlau ib feem ntawm cov khoom siv lead ua nrog koj txhais tes, uas yuav tsis tsuas cuam tshuam rau kev ntsuas, tab sis kuj yuav ua rau hluav taws xob poob siab.
3. Nws yog txwv tsis pub hloov lub zog thaum lub sij hawm ntsuas
Thaum ntsuas qhov tam sim no thiab qhov hluav taws xob ntawm lub voj voog, nws yog txwv tsis pub hloov lub zog tib lub sijhawm, txwv tsis pub lub multimeter yuav yooj yim puas. Tshwj xeeb tshaj yog thaum ntsuas high voltage thiab siab tam sim no, switching gears yog nquag arcing, uas tej zaum yuav hlawv cov hloov hu, uas yog heev txaus ntshai.
Txhawm rau hloov lub zog, koj yuav tsum tshem tawm qhov kev xeem ua ntej, tom qab ntawd hloov lub zog, thiab tom qab ntawd ntsuas.
4. Kev xaiv iav yuav tsum yog los ntawm loj mus rau me me
Thaum qhov ntsuas tam sim no lossis qhov hluav taws xob tsis meej, lub iav siab tshaj plaws yuav tsum raug xaiv ua ntej, thiab tom qab ntawd hloov kho cov iav tsim nyog raws li qhov ntsuas tau, yog li tsis txhob khoov rab koob lossis ua rau lub taub hau puas vim muaj ntau dhau deflection ntawm rab koob.
5. Thaum siv lub multimeter, nws yuav tsum tau muab tso rau kab rov tav
Thaum siv lub multimeter, lub multimeter yuav tsum muab tso rau hauv ib qho chaw tiaj tus, kab rov tav, thiab tig ntsej muag thaum nyeem ntawv kom tsis txhob ua yuam kev.
6. Tsis txhob txuas cov ncej zoo thiab qhov tsis zoo tsis raug
Thaum ntsuas DC tam sim no lossis DC voltage, ceev faj kom tsis txhob thim cov ncej zoo thiab tsis zoo, txwv tsis pub txhais tes yuav tig mus rau qhov sib txawv. Thaum pom tias cov ncej zoo thiab qhov tsis zoo yog thim rov qab, tig cov cwj mem liab thiab dub tam sim kom tsis txhob muaj kev puas tsuaj rau tes, taub hau thiab lwm qhov chaw.
