Introduction:
True 4-wire AC sine measurement, to effectively avoids the impact of test lines and contact resistance. Two functions interface, the old battery sorting function, low power consumption and a variety of power-saving options. Test range up to 200 ohms with a minimum resolution of 0.01 milliohms and less than 5 milliohms. Press HOLD to enable the ZR function to measure internal resistance as low as 0.30-0. 50 milliohms.

Features:
Has a three-level battery rating detection. By setting the voltage resistance rating, the battery can be grouped.
Built-in charging management circuit. And can be set to 200mA and 400mA two charging current.
Energy saving function. Can be set 5 - 60min shutdown delay. No operation and input, the ultra-delayed automatic shutdown. Can be set to 5-30min delay into low power mode.
