Qukaim Battery Tester YR1035 High Precision Battery Internal Resistance Meter Tester, Four-Wire System, Lithium Battery Tester, Accurate Measurement, Compact Design

Features: 1True four-wire 1Khz AC sinusoidal internal resistance meter 0.00001Ω---200Ω range. It can measure lead acid, lithium ion, lithium polymer, lithium iron phosphate, alkaline, dry battery, nickel hydrogen, nickel cadmium, button battery and so on. The ZR function is used to measure the internal resistance of 5 milliohms or l. 2Note: It is forbidden to input AC signal and DC voltage higher than 100V. 3Special combination: Host and probe test line, suitable for measuring various types of batteries, good versatility. Twisted pair of wires to improve anti-interference. 4Made of ABS material, sturdy, and long service life. 5Profional manufacturing, stable characteristics and high reliability. Specification: Item Type: Battery Internal Resistance Tester Model: YR1035 Material: ABS Color: Black Measurement Range: 0V-100V DC, 0.01mΩ-200Ω Charger: 5V Probe Test Wire Length: Approx. 75cm/29.53inch Internal Resistance Measurement: Precision format: ± ([precision percentage] + [least significant digit] Range minimum resolution accuracy 20mΩ 0.01mΩ 0.7%+7 (when ZR function is enabled) 200mΩ 0.1mΩ 0.5%+5 2Ω 1mΩ 0.5%+5 20Ω 10mΩ 0.5%+5 200Ω 0.1Ω 0.6%+5 In the range of 5%-95% of the gear position, if it is not within this range (l than 5% gear range range, or greater than 95% gear range range), the error may be greater than the above accuracy.
