HW-586 Модуль тестер емкости батарей 18650Li-Lead-Acid

Current error: max 1.5%±0.008A Capacity range: 0-9999Ah (1Ah=1000mAh); display scales by decimal point Note: Circuit designed for DC bias to improve voltage accuracy. Empty terminal may show small voltage; true value unaffected. Shorted input shows 0V. Size: 51×37×12mm; Weight: 26g Packing: 51×37×12mm; Gross: 27g Instruction: Fully charge test battery. Connect battery + to +, - to -, then load to + and -, power via micro USB. Battery voltage displays. Press OK to start. It auto-sets end voltage from full charge. Flash 3 times before start. To set end voltage manually, press +/-. End voltage shows P and 0.1V steps. Press OK to start. Test: load on, display shows capacity (Ah), current (A), voltage (V). When voltage reaches set end, load is cut, display stays showing capacity with rapid flash. Press OK to stop flashing and stabilize. Press OK again to reset for next test. Error codes: Err1: battery voltage > 15V Err2: battery voltage < end voltage Err3: load/current poor or high resistance Err4: excessive current (>3.1A) Calibration: Hold all three buttons to enter; shows calibration count, then 0u0A. Short + and - and OK to display J10u. Apply 10.00V across input and press OK to show J2.0A. Apply 2.0A DC output/input and OK. If data is reliable, four digits display and exit; else discard. Note: May vary slightly due to manual measurement, tools, lighting, or camera. 1 × Battery Capacity Tester Module 2 × Load Resistors 4 × Screws 4 × Nuts
