Feature:1. AT528L is a miniature handheld instrument controlled by a high-performance 32-bit ARM microprocessor, with a built-in large-capacity lithium battery to achieve ultra-long standby2. 3.5inch real color LCD screen allows you to read the measurement data, it can judge the degradation of the battery by testing the internal resistance and voltage of the battery.3. Test range from 0.1m to 200, 0 - 50 V DC voltage, maximum reading of the resistance of 3200 dgts and voltage of 3000 dgts. Accurate open voltage can be tested out by vectorless test theory.4. Professional sorting function and sorting sets of the beep make it more suitable for automatic assembly line test.5. It has both portable of minitype and the excellent performance of the bench type. 6. Can be equipped with 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.7. Application Areas: Measuring various low-voltage batteries, batteries, lithium batteries, mobile phone batteries; contact resistance, battery internal resistance, battery voltage; UPS battery detection.Specification:Condition: 100% NewItem Type: Internal Resistance TesterMaterial: ABS+MetalColor: As shown in the pictureVoltage: 100-240Vv:* {behavior:url(#default#VML);}o:* {behavior:url(#default#VML);}x:* {behavior:url(#default#VML);}.shape {behavior:url(#default#VML);}v:* {behavior:url(#default#VML);}o:* {behavior:url(#default#VML);}x:* {behavior:url(#default#VML);}.shape {behavior:url(#default#VML);}ModelAT528LParametersAC resistance(R)DC voltage(U)AccuracyResistance: 0.8%5dgtVoltage: 0.5%5dgtMeasurement RangeResistance: 0.1m~200.0Voltage: 1mV~50VdcSignal SourceAC: 1kHz Open-circuit Voltage: < 30mv(Reduces damage to battery under test), Test Current<15mARangeAutomatic, Manual, Nominal with 4 rangesSpeed2 times/secondResult DisplayABS/PER/SEQMaximum ReadingResistance: 3,200Voltage: 3,000AdjustmentShort-circuit reset for each rangeComparatorVoltage compare separately, resistance compare separately, Voltage and resistance combination compare, GD/NG sorting result display, beepTriggerInternal, Manual, Remote InterfaceBuild-in Mini-USB (virtual serial port); Charging Interface; U disc InterfaceOthers3.5 inches true color 16M color LCD displayKeypad lock and data hold function Compatible SCPI Order Set Switch in both Chinese and EnglishAdjustable background light Large capacity lithium battery to achieve long standby, automatic shutdown500 sets of measurement data are saved with one keyPower RequirementVoltage198VAC~240VACFrequency50HzPower: Maximum 15VADimension & Weight264x107x350mm/10.4x4.2x13.8in(W x H x D)1675g/59.1ozAccessoriesATL501B: 4-terminal kelvin test clipATL909: DC adaptorATL202: Portable bagATL804: Li- batteryPackage List:1 x Host1 x 4-terminal Kelvin Test Clip1 x DC Adaptor1 x Portable Bag1 x Li- battery1 x Mini-USB Cable 1 x English ManualNote:Because there was a manual measuring ,the size may has 1-2inch difference.
