Ukuhlolwa Kokuhlanganiswa Kwama-Multimeter Edijithali ye-LEEM-21 Isithombe Esifakiwe

Ukuhlolwa Kokuhlanganiswa Kwe-LEEM-21 Digital Multimeter

Incazelo emfushane:

Leli thuluzi lichaza isimiso sokusebenza se-chip yokuguqula i-analog-to-digital enamadijithi amathathu nesigamu i-ICL7107, kanye nendlela yokulinganisa amanani ayisisekelo angokwenyama njenge-voltage, ukumelana, kanye namanani wamanje, futhi lisebenzisa abahlukanisi bamandla kagesi, ama-shunt kanye nama-binning resistor ukukala amandla kagesi, ukumelana, kanye namanani wamanje. Ukuhlolwa komklamo wokwandiswa kwebanga, ukuklama kanye nokukala inani le-hFE le-triode kanye nenani lokwehla kwamandla kagesi angaphambili le-diode.

Amapharamitha obuchwepheshe ayinhloko
1. Ububanzi bokumelana: 200Ω, 2KΩ, 20KΩ, 200KΩ, 2MΩ;
2. Ububanzi bamanje: 200μA, 2mA, 20mA, 200mA, 2A;
3. Ububanzi bamandla kagesi: 200mV, 2V, 20V, 200V, 1000V;
4. Ngesekethe yokuguqula i-AC/DC, isekethe yokulinganisa i-diode kanye ne-triode;
5. Iqukethe ikhanda lemitha eliguquliwe elinezinombolo ezintathu nesigamu, isihlukanisi se-voltage, i-shunt, isekethe yokuvikela nezinye izingxenye;
6. Ukunikezwa kwamandla kagesi kwe-DC: 0～2V, 0.2A; 0～20V, 20mA;
7. Umklamo wekesi lensimbi, ugesi we-AC 220V.

Okwedlule: Ukuhlolwa Kokuguqulwa Nokulinganiswa Kwamamitha Kagesi e-LEEM-20 (i-Milliammeter)

Olandelayo: Ukuhlolwa Kokulinganisa Ukumelana Kwesiphetho Esine se-LEEM-22
