Hoʻokolohua LEEM-18 AC Bridge

Nā hoʻokolohua
1. E aʻo a hoʻomaopopo i nā kūlana kaulike a me nā loina ana o ke alahaka AC; e hōʻoia i nā kūlana kaulike o ke alahaka AC;
2. E ana i ka capacitance a me ka pohō dielectric; ka inductance ponoʻī a me kāna kumu maikaʻi coil a me ka inductance like a me nā ʻano uila ʻē aʻe.
3. E hoʻolālā i nā alahaka AC like ʻole no ke ana maoli.

Nā palena loea nui
1. Kumu hōʻailona mana i kūkulu ʻia: alapine (frequency) 1kHz ± 10Hz, ka nui o ke anakahi uila hoʻopuka: 1.5Vrms;
2. Hōʻikeʻike kikohoʻe i kūkulu ʻia AC voltmeter: pae ana o ke ana uila AC: 0～2V, hōʻikeʻike kikohoʻe ʻekolu a me ka hapa;
3. Mīkini alapine uila LED ʻehā huahelu i kūkulu ʻia, ka laulā ana: 20Hz～10kHz, hewa ana: 0.2%;
4. Kuhikuhi ʻole AC i kūkulu ʻia: me ka pale ʻana i ka overload, ʻaʻohe poʻo mika; ʻike ≤1 × 10-8A / div, hiki ke hoʻololi mau ʻia;
5. Ke kū'ē ʻana o ka lima o ke alahaka i kūkulu ʻia:
ʻO Ra: aia i loko o ʻehiku mau pale AC o 1, 10, 100, 1k, 10k, 100k, 1MΩ, me ka pololei o 0.2%
Rb: Hana ʻia me kahi pahu pale AC 10 × (1000 + 100 + 10 + 1 + 0.1) Ω, me ka pololei o 0.2%
Rn: Hana ʻia me kahi pahu pale AC 10K+10×(1000+100+10+1)Ω, me ka pololei o 0.2%
6. ʻO ka capacitor maʻamau i kūkulu ʻia ʻo Cn, ka inductance maʻamau Ln;
Ka capacitance maʻamau: 0.001μF, 0.01μF, 0.1μF, pololei 1%;
Inductance maʻamau: 1mH, 10mH, 100mH, pololei 1.5%;
7. Ua hoʻokomo ʻia ke kū'ē Rx i ana ʻia, capacitance CX a me ka inductance LX me nā waiwai like ʻole a me nā hana.
