LIOKM YR1035+ - Lithium Battery Internal Resistance Tester 4-Wire

A real four-wire internal resistance tester, which can test internal resistance and voltage at the same time, and can also be used for resistance measurement. Measurement results are displayed on the same screen. This product is suitable for battery matching, battery performance testing, battery screening, etc. The machine is compact and easy to carry. It is your electrician and electronics testing machine. True 4-wire AC sinusoidal measurement effectively rejects the effects of test lead and contact resistance. Two functional interfaces, battery sorting function. Built-in battery, mobile phone charger charging, low power consumption + multiple power saving options. The maximum test range is 200 ohms, and the minimum resolution is 0.01 milliohms, less than 5 milliohms. Press HOLD to enable the ZR function to measure internal resistance down to 0.30-0.50 milliohms. Handcrafted with an overly discreet look on the right. It can measure lead acid, lithium , lithium polymer, lithium iron phosphate, alkaline battery, dry battery, nickel metal hydride, nickel cadmium, button battery, etc. Built-in charging management circuit. And two charging currents of 200mA and 400mA can be set. Energy saving function. 5-60 minutes shutdown delay can be set. There is no operation or input, and it will automatically shut down after an over-delay. Can be set to delay entry into low power mode from 5-30 minutes. Specifications: Material: Plastic Voltage measurement range: 0-28 Internal resistance measurement range: 0-200 Battery: 2000mAh
