Kev Hloov Kho thiab Kev Ntsuas Hluav Taws Xob LEEM-20 (Milliammeter)

Kev sim
1. Kev hloov kho thiab kev ntsuas lub ammeter;
2. Kev hloov kho thiab kev ntsuas ntawm voltmeter;
3. Kev hloov kho thiab tsim qauv ntawm ohmmeter.

Cov txheej txheem tseem ceeb
1. Lub ntsuas hom pointer refitted: ntsuas ntau yam 1mA, sab hauv tsis kam txog 155Ω, qhov tseeb 1.5;
2. Lub thawv tsis kam: qhov ntau thiab tsawg hloov kho yog 0 ~ 11111.0Ω, thiab qhov tseeb yog 0.1 theem;
3. Tus qauv ammeter: 0 ~ 2 mA, 0 ~ 20mA ob qhov ntau thiab tsawg, peb thiab ib nrab cov zaub digital, qhov tseeb ± 0.5%;
4. Tus qauv voltmeter: 0 ~ 2V, 0 ~ 20V ob qhov ntau thiab tsawg, peb thiab ib nrab cov zaub digital, qhov tseeb ± 0.5%;
5. Qhov chaw ruaj khov kho tau: tso zis 0 ~ 2V, 0 ~ 10V ob lub zog, ruaj khov 0.1% / feeb;
6. Cov neeg siv uas xav tau nws tuaj yeem ua rau kom muaj kev tiv thaiv ob txoj kev ntawm lub taub hau 'meter', yog li ntawd cov koob txhaj tshuaj yuav tsis raug puas tsuaj!
