Yuav ua li cas siv Fieldpiece multimeter
Kab lus no yuav qhia koj yuav ua li cas siv lub teb multimeter.
Ua ib tus neeg cog lus, kuv tau siv Fieldpiece multimeters rau kuv cov haujlwm, yog li kuv muaj ob peb lub tswv yim los qhia. Koj tuaj yeem ntsuas tam sim no, tsis kam, voltage, capacitance, zaus, txuas ntxiv thiab kub.
Nyeem nrog thaum kuv taug kev nrog koj los ntawm kuv phau ntawv qhia ntxaws.
Ib feem ntawm lub teb multimeter
- RMS wireless pliers
- Cov khoom siv coj mus kuaj
- Alligator Clamps
- Thermocouple hom K
- Velcro
- alkaline roj teeb
- Kev tiv thaiv soft case
Yuav ua li cas siv Fieldpiece multimeter
1. Kev kuaj hluav taws xob
- Txuas qhov kev xeem coj mus rau cov connectors. Koj yuav tsum txuas cov hlau lead dub mus rau "COM" jack thiab cov hlau lead liab mus rau "+" jack.
- Teem lub xov tooj mus rau VDC hom txhawm rau txheeb xyuas qhov hluav taws xob DC ntawm cov laug cam. (1)
- Taw tes thiab kov cov probes mus rau qhov chaw kuaj.
- Nyeem cov ntsuas.
2. Siv Fieldpiece multimeter los ntsuas kub
- Tshem tawm cov xov hlau thiab txav TEMP hloov mus rau sab xis.
- Ntxig Hom K thermocouple ncaj qha rau hauv lub qhov sib npaug.
- Kov qhov kawg ntawm qhov ntsuas kub (hom K thermocouple) ncaj qha rau cov khoom kuaj.
- Nyeem cov txiaj ntsig.
Lub 'meter' qhov sib txuas txias ua kom ntsuas qhov tseeb txawm tias qhov kub thiab txias hloov pauv dav.
3. Siv cov hluav taws xob tsis sib cuag (NCV)
Koj tuaj yeem sim 24VAC los ntawm lub ntsuas cua sov lossis nyob voltage txog 600VAC nrog NCV. Nco ntsoov xyuas qhov chaw nyob paub ua ntej siv. Daim duab ntu yuav qhia pom muaj qhov hluav taws xob thiab lub teeb liab LED. Raws li lub zog teb nce, lub suab nrov hloov los ntawm kev sib tshuam mus tas li.
4. Ua ib qho kev ntsuas txuas ntxiv nrog Fieldpiece Multimeter
Lub HVAC teb multimeter kuj yog ib qho cuab yeej zoo tshaj plaws rau kev soj ntsuam txuas ntxiv. Nov yog qhov koj tuaj yeem ua tau:
- Tua lub fuse. Koj tsuas yog yuav tsum rub lub lever kom tua lub zog.
- Siv ib daim teb multimeter thiab teeb nws mus rau hom tsis tu ncua.
- Kov cov kev sojntsuam multimeter rau txhua qhov fuse.
- Yog tias koj lub fuse tsis muaj qhov txuas ntxiv, nws yuav beep. Txawm li cas los xij, DMM yuav tsis kam beep yog tias muaj kev txuas ntxiv hauv koj lub fuse.
5. Tshawb xyuas qhov sib txawv ntawm qhov voltage nrog lub teb multimeter.
Hwj chim surges yuav ua tau txaus ntshai. Yog li ntawd, nws tsim nyog xyuas koj lub fuse thiab pom tias nws nyob ntawd. Tam sim no coj ib daim teb multimeter thiab ua raws li cov lus qhia hauv qab no:
- Qhib lub fuse; xyuas kom nws tseem ciaj sia.
- Siv lub teb multimeter thiab teeb tsa rau voltmeter (VDC) hom.
- Muab multimeter coj mus rau txhua qhov kawg ntawm lub fuse.
- Nyeem cov txiaj ntsig. Nws yuav qhia xoom volts yog tias tsis muaj qhov sib txawv voltage hauv koj lub fuse.
Cov lus nug nquag nug
Dab tsi yog cov yam ntxwv ntawm lub teb multimeter?
- Thaum ntsuas qhov hluav taws xob ntau dua 16 VAC. DC / 35V DC Tam sim no, koj yuav pom tias lub teeb ci LED thiab lub suab nrov yuav suab lub tswb. Qhov no yog ib qho kev ceeb toom overvoltage.
- Teem lub gripper rau NCV (tsis tiv tauj voltage) txoj hauj lwm thiab taw tes nws ntawm qhov yuav muaj qhov hluav taws xob. Kom paub tseeb tias qhov chaw yog "kub", saib lub ci RED LED thiab lub suab nrov.
- Lub thermocouple tsis txuas tom qab lub sijhawm luv luv ntawm qhov ntsuas hluav taws xob vim qhov kub hloov pauv.
- Nws suav nrog lub zog txuag hluav taws xob hu ua APO (Auto Power Off). Tom qab 30 feeb ntawm kev tsis ua haujlwm, nws yuav cia li kaw koj lub ntsuas. Nws twb tau qhib los ntawm lub neej ntawd thiab APO tseem yuav tshwm sim ntawm qhov screen.
Qhov ntsuas LED qhia li cas?
High voltage LED - Koj tuaj yeem pom nws ntawm sab laug thiab nws yuav beep thiab teeb thaum koj tab tom kuaj xyuas qhov hluav taws xob siab. (2)
Txuas ntxiv LED - Koj tuaj yeem pom nws ntawm sab xis thiab nws yuav beep thiab teeb thaum koj tshawb xyuas txuas ntxiv.
Qhov taw qhia tsis sib cuag voltage - Koj tuaj yeem pom nws hauv nruab nrab thiab nws yuav beep thiab teeb pom kev thaum koj siv qhov ntsuas ntsuas qhov ntsuas qhov tsis sib cuag.
Dab tsi yuav tsum xav txog thaum siv lub teb multimeter?
Nov yog qee yam uas yuav tsum xav txog thaum siv lub teb multimeter:
- Thaum ntsuas, tsis txhob kov cov kav hlau qhib, qhov (socket), fittings thiab lwm yam khoom.
- Ua ntej qhib lub tsev, tshem tawm cov kev xeem coj mus kuaj.
- Tshawb xyuas qhov kev xeem ua rau kev puas tsuaj los yog cov kab hluav taws xob raug. Yog tias nws yog, hloov nws.
- Thaum ntsuas, tuav koj lub ntsis ntiv tes tom qab tus ntiv tes saib xyuas ntawm qhov kev sojntsuam.
- Yog ua tau, sim nrog ib txhais tes. High voltage transients tuaj yeem ua puas lub meter mus tas li.
- Tsis txhob siv cov khoom siv multimeters thaum muaj cua daj cua dub.
- Tsis txhob tshaj qhov ntsuas qhov ntsuas ntawm 400 A AC thaum ntsuas cov zaus AC tam sim no. RMS clamp meter tuaj yeem tau txais kub tsis txaus yog tias koj tsis ua raws li cov lus qhia.
- Tig lub xov tooj mus rau OFF txoj hauj lwm, tshem tawm cov kev xeem coj thiab unscrew lub npog roj teeb thaum hloov lub roj teeb.
