Cov voltmeters digital ib txwm muaj qhov tsis kam sab hauv tsuas yog 10MΩ, uas ua rau muaj qhov yuam kev loj thaum ntsuas cov khoom tiv taus siab. Lub tshuab ntsuas siv cov voltmeter tiv taus sab hauv siab heev uas loj dua 1000MΩ, txo qhov yuam kev ntawm lub kaw lus. Rau cov resistors ib txwm muaj tsawg dua 1MΩ, qhov yuam kev ntawm lub kaw lus los ntawm qhov tsis kam sab hauv ntawm voltmeter tuaj yeem tsis quav ntsej, tsis hais lub voltmeter sab hauv thiab sab nraud; rau qhov tsis kam siab, phototube thiab lwm yam khoom loj dua 1MΩ kuj tuaj yeem ntsuas tau raug. Yog li, cov kev sim yooj yim ib txwm muaj los nthuav cov ntsiab lus ntawm cov kev sim tshiab.

Cov ntsiab lus tseem ceeb ntawm kev sim
1, kev ntsuas cov yam ntxwv ntawm resistor voltammetric; diode thiab voltage regulator diode voltammetric yam ntxwv nkhaus ntsuas.
2, kev ntsuas cov yam ntxwv ntawm volt-ampere ntawm lub teeb-emitting diodes, tungsten qhov muag teev.
3, kev sim tshiab: kev ntsuas ntawm volt-ampere cov yam ntxwv ntawm kev tiv taus siab thiab capacitance.
4, Kev sim tshawb nrhiav: kev kawm txog kev cuam tshuam ntawm qhov tsis kam sab hauv ntawm lub 'meter' ntawm kev ntsuas cov yam ntxwv volt-ampere.

Cov kev tsis tseem ceeb
1, los ntawm kev tswj hwm lub zog fais fab, hloov pauv resistor, ammeter, siab-resistance voltmeter thiab cov khoom nyob rau hauv kev sim, thiab lwm yam.
2, DC tswj fais fab mov: 0 ~ 15V, 0.2A, muab faib ua ob qib ntawm kev sib piv thiab kev sib piv zoo, tuaj yeem hloov kho tas li.
3, lub ntsuas hluav taws xob sab hauv uas muaj zog heev: plaub thiab ib nrab tus lej zaub, ntau yam 2V, 20V, qhov sib npaug ntawm cov tswv yim impedance> 1000MΩ, kev daws teeb meem: 0.1mV, 1mV; 4 qhov ntau ntxiv: kev tiv thaiv sab hauv 1 MΩ, 10MΩ.
4, ammeter: plaub thiab ib nrab tus lej zaub 'meter' taub hau, plaub qhov ntau thiab tsawg 0 ~ 200μA, 0 ~ 2mA, 0 ~ 20mA, 0 ~ 200mA, sab hauv tsis kam, raws li.
0 ~ 200mA, sab hauv tsis kam ntawm: 1kΩ, 100Ω, 10Ω, 1Ω, feem.
5, lub thawv tsis kam hloov pauv: 0 ~ 11200Ω, nrog rau lub voj voog tiv thaiv tam sim no zoo meej, yuav tsis hlawv cov khoom.
6, cov khoom ntsuas: resistors, diodes, voltage regulators, lub teeb-emitting diodes, lub teeb me me, thiab lwm yam.
