LEEM-23 Whakamatau Piriti Maha

Tawhā hangarau matua
1. Piriti ringa parenga R1: Whirihorahia he huinga parenga tino tika: 10Ω, 100Ω, 1000Ω, 10kΩ, ka hurihia e te hononga mono ara-poto, me te tika o te parenga he ±0.1%;
2. Piriti ringa parenga R2: Whirihorahia he huinga pouaka parenga: 10×(1000+100+10+1)Ω, ko te tika ātete: ±0.1%, ±0.2%, ±1%, ±2%;
3. Piriti ringa parenga R3: Whirihorahia e rua nga huinga pouaka parenga R3a, R3b, kua whakauruhia a roto ki runga i te pana whakawhiti paparua-rua, ka huri te parenga i te wa kotahi: 10×(1000+100+10+1+0.1)Ω , ātete
Ko te tika: ±0.1%, ±0.2%, ±1%, ±2%, ±5%;
4. Paerewa parenga RN: Ko nga uara parenga ko: 10Ω, 1Ω, 0.1Ω, 0.01Ω, me nga tohu tika ātete
I tua atu i: ± 0.1%, ± 0.1%, ± 0.2%, ± 0.5%, ka taea te hono ki waho;
5. Ko te parenga i hangaia hei ine: Rx kotahi: 1kΩ, 0.25W, koretake: 0.1%;Rx rua: 0.2 ohm, 0.25W, rangirua: 0.2%.Ka taea te whakamahi i enei parenga e rua ki te whakatikatika i te piriti, ki te whakamatautau ranei kei te pai te mahi o te piriti.
6. Irirangi Mamati: whakamahi i te 4 me te haurua iri hiko whakaatu mamati: 200mV, 2V te awhe.Ko te tika o te whakaaturanga o te galvanometer mamati ko: (0.1% awhe ± 2 kupu).Ka taea te hono o te Galvanometer ki waho;
7. Whakawhiwhi hiko maha-mahi: 0～2V tuku hiko taea te whakarite, 3V, 9V tuku hiko.
8. Ina whakamahia te taputapu hei piriti ringa kotahi, ko te awhe ine: 10Ω～1111.1KΩ, 0.1 taumata;
9. Ina whakamahia te taputapu hei piriti hiko ringa-rua, te awhe ine: 0.01～111.11Ω, 0.2 taumata;
10. Ko te awhe whai hua o te piriti kore taurite ko 10Ω～11.111KΩ, ko te hapa e whakaaetia ana ko te 0.5%;
11. I te wa e whakatuu ana i te piriti kore taurite, me whakauru te taputapu ki te pukoro parenga, ki te taputapu whakahaere pāmahana ranei.
12. Ka taea te whakarite i nga momo piriti hiko rite.
