Feem ntau siv txoj hauv kev thiab kev daws teeb meem rau digital clamp meters
1. Kev ntsuas tam sim no AC
① Tig qhov hloov mus rau ACA1000A.
② Khaws qhov hloov mus rau hauv lub xeev so.
③ Nias lub khawm kom qhib lub puab tsaig thiab tuav ib lub xaim. Yog tias ntau tshaj ob lub xov hlau raug clamped, qhov ntsuas yuav siv tsis tau.
④ Nyeem tus nqi. Yog tias qhov kev nyeem ntawv tsawg dua 200A, tig mus rau ACA200A txhawm rau txhim kho qhov tseeb. Yog tias nws tsis tuaj yeem nyeem ncaj qha hauv qhov tsaus ntuj vim yog ib puag ncig ib puag ncig, nias lub khawm tuav thiab nyeem hauv qhov chaw ci.
2. AC thiab DC voltage ntsuas
① Thaum ntsuas DC voltage, tig mus rau ACA200A. Thaum ntsuas AC voltage, tig mus rau ACV750V.
② Khaws qhov hloov mus rau hauv lub xeev so.
③ Cov hlau kuaj liab txuas nrog "V / Ω" lub davhlau ya nyob twg, thiab cov hlau kuaj dub txuas nrog lub davhlau ya nyob twg "COM".
④ Cov kev xeem liab thiab xim dub tau txuas nrog rau tib lub voj voog hauv kev sim.
3. Kev ntsuas ntsuas
① Tig qhov hloov mus rau qhov hluav taws xob thaiv ntawm qhov tsim nyog.
② Khaws qhov hloov mus rau hauv lub xeev so.
③ Cov hlau kuaj liab txuas nrog "V / Ω" lub davhlau ya nyob twg, thiab cov hlau kuaj dub txuas nrog lub davhlau ya nyob twg "COM".
④ Cov kev xeem liab thiab dub yog txuas nrog rau ob qho kawg ntawm cov resistor nyob rau hauv kev sim. Thaum ntsuas cov kab tsis kam, cov kab yuav tsum raug txiav tawm ntawm qhov chaw, thiab cov resistor txuas yuav tsum tau tawm.
4. Kev sim txuas ntxiv
① Tig qhov hloov mus rau 200n.
② Cov kev xeem liab thiab dub yog txuas nrog "V / Ω davhlau ya nyob twg thiab COM" davhlau ya nyob twg.
③Yog tias qhov kev tiv thaiv ntawm qhov kev xeem liab thiab xim dub yog tsawg dua (50 ± 25)Ω, lub buzzer built-in yuav suab.
1-Clamp taub hau 2-Clamp taub hau trigger 3-Tuav hloov 4-Rotary hloov 5-Display 6-Insulation test accessory interface 7-Public av davhlau ya nyob twg 8-Voltage resistance input davhlau ya nyob twg 9-Portable pluaj.
5. Kev ntsuas kev ua haujlwm siab
① Tig qhov hloov mus rau "EXTERNALUNlT" 20MΩ lossis 2000MΩ txoj haujlwm.
②Tus nqi tso tawm tsis ruaj khov thiab nyob hauv lub xeev dawb.
③Ntxig 3 plugs ntawm cov khoom siv kuaj rau hauv 3 lub tswv yim jacks ntawm lub ntsuas ntsuas.
④ Lub clamp meter hloov thiab qhov hloov pauv ntawm cov khoom siv ntsuas tau teeb tsa rau 2000MΩ txoj haujlwm.
⑤ Lub ntsiab lus nkag ntawm cov khoom siv kuaj tau txuas nrog qhov kev tiv thaiv nyob rau hauv kev sim;
⑥ Muab cov khoom siv kuaj hauv qhov "ON" txoj haujlwm, nias lub pob "PUSH", qhov taw qhia lub teeb yuav teeb, thiab cov zaub yuav qhia tus nqi ntsuas. Yog tias qhov kev nyeem ntawv tsawg dua 19MΩ, xaiv 20MΩ ntau yam rau cov khoom siv ntsuas ntsuas clamp txhawm rau txhim kho qhov tseeb. Siv.
