LEEM-18 AC Alahaka hoao
Nā hoʻokolohua
1. E aʻo a haku i nā kūlana kaulike a me nā loina ana o ke alahaka AC;hōʻoia i nā kūlana kaulike o ke alahaka AC;
2. E ana i ka capacitance a me ka poho dielectric;inductance pono'ī a me kāna kumu waiwai coil a me ka inductance like a me nā ʻāpana uila ʻē aʻe.
3. E hoʻolālā i nā alahaka AC like ʻole no ke ana maoli.
ʻO nā palena ʻenehana nui
1. Ke kumu hōʻailona mana i kūkulu ʻia: alapine 1kHz±10Hz, amplitude voltage pukana: 1.5Vrms;
2. Hōʻike kikohoʻe i kūkulu ʻia i loko o ka voltmeter AC: ʻO ke ana ʻana o ke kaha uila: 0~2V, ʻekolu a me ka hapa hōʻike kikohoʻe;
3. ʻEha-helu LED kikohoʻe alapine mika, ana laulā: 20Hz~10kHz, ana hewa: 0.2%;
4. ʻO AC zero-pointer i kūkulu ʻia: me ka pale ʻana i ka overload, ʻaʻohe poʻo mika;sensitivity ≤1×10-8A/div, hiki ke hoʻololi mau ʻia;
5. Paʻa lima alahaka i kūkulu ʻia:
Ra: ʻehiku mau pale AC o 1, 10, 100, 1k, 10k, 100k, 1MΩ, me ka pololei o 0.2%
Rb: Hana ʻia me kahi pahu kūʻē AC 10×(1000+100+10+1+0.1)Ω, me ka pololei o 0.2%
Rn: Hana ʻia me kahi pahu kūʻē 10K+10×(1000+100+10+1)Ω AC, me ka pololei o 0.2%
6. Hoʻokomo ʻia ka capacitor maʻamau Cn, Ln inductance maʻamau;
Ka mana maʻamau: 0.001μF, 0.01μF, 0.1μF, pololei 1%;
Inductance maʻamau: 1mH, 10mH, 100mH, pololei 1.5%;
7. Hoʻokomo ʻia ka Rx resistance i ana ʻia, capacitance CX a me inductance LX me nā waiwai like ʻole a me nā hana.
