Battery Tester, Lithium Battery Internal Resistance Tester 4-Wire YR1035+/YR1030+ High Accuracy Electric Vehicle Group Battery Tester(YR1030 Plus)

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: PlasticVoltage measurement range: 0-28Internal resistance measurement range: 0-200Battery: 2000mAh

• The minimum resolution can reach 0.01 milliohms, which is convenient for testing large capacity, high discharge rate and low internal resistance batteries. The measuring range can reach 200 ohms, and it can measure low-capacity, low-current and high internal resistance batteries such as button batteries and laminated batteries.
• Separate test function for voltage and internal resistance, with manual and automatic range function. The automatic range switching is stable and fast, the measurement display is updated 4 times per second, and the time range can be locked at about 1S to display stably. The HOLD function helps you lock the display for easier reading.
• Using dot matrix LCD screen. Dimension font combination can not only clearly display the measurement results, but also display rich content.
• 2 display modes. The normal mode screen displays the internal resistance and voltage, and the sorting mode displays the internal resistance voltage and the level of the battery classification count.
• With three levels of battery rating detection. By setting withstand voltage ratings, batteries can be grouped.
