LEEM-20 Electric Meter Modification and Calibration Experiment (Milliammeter)

Kev sim
1. Ammeter hloov kho thiab calibration;
2. Kev hloov kho thiab calibration ntawm voltmeter;
3. Kev hloov kho thiab tsim ntawm ohmmeter.

Lub ntsiab technical parameters
1. Pointer hom refitted meter: ntsuas ntau yam 1mA, sab hauv tsis kam txog 155Ω, precision 1.5;
2. Lub thawv tsis kam: qhov kev hloov pauv yog 0～11111.0Ω, thiab qhov tseeb yog 0.1 qib;
3. Tus qauv ammeter: 0～2 mA, 0 ~ 20mA ob chav, peb thiab ib nrab ntawm cov zaub, qhov tseeb ± 0.5%;
4. Tus qauv voltmeter: 0 ~ 2V, 0 ~ 20V ob chav, peb thiab ib nrab ntawm cov zaub, qhov tseeb ± 0.5%;
5. Adjustable stabilized voltage qhov chaw: tso zis 0 ~ 2V, 0 ~ 10V ob lub zog, stability 0.1% / min;
6. Cov neeg siv uas xav tau nws tuaj yeem ua kom muaj kev tiv thaiv ob-txoj kev ntawm lub taub hau meter, kom cov koob yuav tsis raug puas tsuaj!
