Mea Hana Hoʻokolohua Piha LEEM-19 no ke Kaapuni AC/DC a me ke Alahaka

Wehewehe Pōkole:

Hoʻohui ka mea hana i nā ʻano hoʻokolohua like ʻole e like me ke alahaka DC (me ke alahaka lima hoʻokahi, ke alahaka lima pālua, ke alahaka kaulike ʻole), ke alahaka AC, ka pane RLC transient a me ka pane paʻa, a he mea hana multifunctional piha loa ia.

1. Ke kū'ē ʻana o ka lima o ke alahaka R1: 1Ω, 10Ω, 100Ω, 1000Ω, 10kΩ, 100kΩ, 1MΩ.
Pololei ±0.1%;
2. Ke kū'ē'ē lima o ke alahaka R2: e hoʻonohonoho i kahi hoʻonohonoho o nā pahu kū'ē: 10kΩ+10×(1000+100+10+1)Ω, pololei ±0.1%;
3. Ke kū'ē ʻana o ka lima o ke alahaka R3: E hoʻonohonoho i ʻelua mau pahu kū'ē synchronous R3a, R3b, i hoʻokomo ʻia i loko ma ka hoʻololi hoʻoili pālua like, a loli ke kū'ē synchronously: 10 × (1000 + 100 + 10 + 1 + 0.1) Ω, ʻO ka pololei: ± 0.1%;
4. Pahu Capacitor: 0.001 ~ 1μF, ʻanuʻu liʻiliʻi loa 0.001μF, pololei 2%;
5. Pahu Inductance: 1～110mH, ʻanuʻu liʻiliʻi loa 1mH, pololei 2%;
6. Lako mana hana he nui: Lako mana hiki ke hoʻololi ʻia DC 0～2V, nalu sine 50Hz～100kHz; nalu huinaha 50Hz
～1kHz; hōʻike ʻia ke alapine (frequency) e kahi helu alapine (frequency counter) 5-huahelu;
7. AC a me DC dual-purpose digital galvanometer: hoʻohana i ka voltmeter hōʻike kikohoʻe: ʻo ka laulā he 200mV, 2V; hiki ke koho i nā ʻano hoʻokomo AC, DC, ʻekolu mau ʻano kaulike ʻole, aia kahi potentiometer hoʻoponopono ʻike.
8. Ke hoʻohana ʻia ka mea hana ma ke ʻano he alahaka lima hoʻokahi, ʻo ka laulā ana: 10Ω～1111.1KΩ, pae 0.1;
9. Ke hoʻohana ʻia ka mea hana ma ke ʻano he alahaka uila lima pālua, ʻo ka pae ana: 0.01～111.11Ω, pae 0.2;
10. ʻO ka laulā kūpono o ke alahaka kaulike ʻole he 10Ω～11.111KΩ, a ʻo ka hewa i ʻae ʻia he 0.5%;
11. Aia ʻelua ʻano o ke kū'ē i ana ʻia i loko o ka mea hana: RX hoʻokahi, RX pālua, ʻelua ʻano o nā capacitors me nā mana like ʻole a me nā pohō like ʻole; ʻelua ʻano o nā inductances me nā inductances like ʻole a me nā waiwai Q like ʻole;
12. Hoʻohālikelike ʻia ke alahaka uila kaulike ʻole me ka sensor mahana thermistor, a ua hoʻolālā ʻia ka thermometer kikohoʻe linear me ka hoʻonā o 0.01 ℃; hiki ke hoʻohana ʻia ka thermistor me ka sensor mahana o ka mea hana hoʻokolohua sensor maʻamau.
13. Hoʻokolohua noiʻi: e aʻo i ka pilina ma waena o ka capacitance, ka pohō a me ke voltage bias;
14. Hoʻokolohua noiʻi: e aʻo i ka pilina ma waena o ka inductance a me ke au bias.
