Battery Internal Resistance Tester High Precision Measuring Instrument
Cov cuab yeej no tau txais kev ua haujlwm siab ib leeg-crystal microcomputer nti tuaj ntawm ST Microelectronics, ua ke nrog American "Microchip" high-resolution A / D hloov dua siab tshiab nti raws li kev ntsuas ntsuas, thiab qhov tseeb 1.000KHZ AC zoo tam sim no ua los ntawm theem -locked voj yog siv los ntsuas qhov teeb liab siv rau ntawm qhov ntsuas qhov ntsuas. Qhov tsim hluav taws xob tsis muaj zog poob lub teeb liab yog ua tiav los ntawm high-precision ua haujlwm amplifier, thiab cov khoom siv sab hauv kuj raug tshuaj xyuas los ntawm cov lim dej ntse. Thaum kawg, nws tau tso tawm rau ntawm lub vijtsam loj dot matrix LCD.
Cov cuab yeej muaj qhov zoo ntawmsiab precision, tsis siv neeg cov ntaub ntawv xaiv, tsis siv neeg polarity kev ntxub ntxaug, ntsuas ceev thiab ntsuas ntau yam.
