Baterei Internal Resistance Tester High Precision Measuring Instrument
Instrumen iki nganggo chip mikrokomputer kristal tunggal kinerja dhuwur sing diimpor saka ST Microelectronics, digabungake karo chip konversi A / D resolusi dhuwur "Microchip" Amerika minangka inti kontrol pangukuran, lan arus positif AC 1.000KHZ sing tepat sing disintesis dening fase. -loop dikunci digunakake minangka sumber sinyal pangukuran ditrapake ing unsur dites. Sinyal gulung voltase lemah sing digawe diproses dening amplifier operasional kanthi tliti dhuwur, lan nilai resistensi internal sing cocog dianalisis kanthi filter digital sing cerdas. Pungkasan, ditampilake ing LCD dot matrix layar gedhe.
Instrumen kasebut nduweni kaluwihanpresisi dhuwur, pilihan file otomatis, diskriminasi polaritas otomatis, pangukuran cepet lan sawetara pangukuran sudhut.
