["Description:\n\nFeatures:\nbrand new and high quality\nTrue 4-wire AC sine measurement, effectively avoid the influence of the test line and contact resistance.\nTwo functions interface, the original battery sorting function.\nBuilt-in battery, mobile phone charger to charge, low power consumption + a variety of power-saving options.\nTest range up to 200 ohms with a minimum resolution of 0.01 milliohms and less than 5 milliohms.\nPress HOLD to enable the ZR function to measure internal resistance as low as 0.30-0.50 milliohms.\nIt can measure lead acid, lithium ion, lithium polymer, lithium iron phosphate, alkaline, dry battery, nickel hydrogen, nickel cadmium, button battery and so on. \n \nNote: Read the instructions and instructions on the back of the instrument before using. It is forbidden to enter the ac signal and the for dc voltage higher than 100 v.\n\nSpecification:\nInternal resistance measurement:\nPrecision format: ± ([precision percentage] + [least significant digit]\nRange minimum resolution accuracy\n20mΩ 0.01mΩ 0.7%+7 (when ZR function is enabled)\n200mΩ 0.1mΩ 0.5%+5\n2Ω 1mΩ 0.5%+5\n20Ω 10mΩ 0.5%+5\n200Ω 0.1Ω 0.6%+5\nIn the range of 5%-95% of the gear position, if it is not within this range (less than 5% gear range range, or greater than 95% gear range range), the error may be greater than the above accuracy\nVoltage measurement:\nRange Accuracy ± (% reading + % range)\n1V 0.15+0.015\n10V 0.15+0.010\n100V 0.15+0.015\nPositive and negative symmetry error ± (0.012% + 5 words)\nTemperature drift within normal use temperature (10°C-40°C) 100ppm/°C\nColor: As pictures shown.\nSize: app. 6x17cm(2.36x6.69in)\nQuantity: 1 set\n\nNote:\nTransition: 1cm=10mm=0.39inch\nNo retail package.\nPlease allow 1-3cm error due to manual measurement. pls make sure you do not mind before you bid.\nDue to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!\n\nPackage includes:\n1 x Host\n1 x 18650 Test Rack\n1 x Kelvin Clip\n1 x Probe Test Line(suitable for measuring battery type is more, corresponding to a variety of situations)\n(other accessories demo in the picture is not included.)"]
