AT528 Handheld Battery Tester For Laptop Battery,AC Resistance Meter And Battery Internal Resistance Tester  AT528 Minitype Handheld Micro ohm Meter adopts high-cost performance 32 bit micro-processor control, designed for large and middle lead acid battery. It can judge the degradation of the battery by testing the internal resistance and voltage of the battery. Test range from 0.01m~2.000k, 0 - 50 V DC voltage, max reading of the resistance of 2200 dgts and voltage of 5000 dgts.Accurate open voltage can be tested out by vectorless test theory. Professional sorting function and sorting sets of the beep make it's more suitable for automatic assembly line test.  AT528 has both portable of minitype and the excellent performance of the bench type. Optional USB interface which can be used for remote control and data acquisition and analysis makes it more suitable for assembly line test of all kinds of batteries.       Feature:           -Gorgeous dual-colure cast shell     -Battery and external power supply     -TFT-LCD Display     -Battery capacity: continuously used for over 8 hours     -Automatic power off     -Double display: ABS/%/Sorting Result     -Comparator Function: GD/NG VFD Show or HANDLER out     -Auto Zero-Adjust for each range     -Four-terminal resistance measurement     -Mini-USB interface     -SCPI compatible command sets     -Keypad lock function     -Data Hold function     -Adjustable background-lightness     -Max power5W     -8.4V,Li-Battery 2200mAh rechargeable battery     -Dimension: 210.76mm*130.23mm*37.88mm                             Application:                 -Internal resistance and voltage of the battery        -Alkaline batteries, lead batteries Life assessment        -UPS Online Measurement        -Batteries identification test        -Supper Capacitor ESR Measurement        -Contact resistance
