The AT35 uses a 0.96-inch IPS high-definition color LCD display to display the state of charge of the appliance, voltage, current, capacity, energy, power, equivalent impedance, temperature and other indicators at a glance. 160 degree wide viewing angle, high brightness and long working life. Voltage: 3.7-30V; Current: 0-4A.Fast charge recognition, widely compatible. Supports QC2.0, QC3.0, 2.4A/2.1A/1A/0.5A, Andriod DCP,- charge protocol identification, let you know the state of charge of the phone.5-bit resolution for more accurate measurements. The screen can be turned off with one button and has a flip screen function. Thermometer function using high-precision thermistor sensor, celsius and fahrenheit free switching.AT35 has power-off storage function, which can store capacity and energy data when the mobile power is cut off, which is convenient for subsequent viewing and convenient for capacity energy measurement of mobile power.Note: Other USB testers that do not have a power-down storage function cannot test capacity and energy.Measure the quality of the charger: connect the same load, compare the no-load and the load, the greater the voltage drop, the worse the charger capacity is, the worse the quality; the voltage drop is not obvious or the voltage rises, the load capacity of the charger and the quality be better.Capacity measurement range: 0-99999mAhEnergy measurement range: 0-99999mAh-999.99WhLoad impedance measurement range: 1 ohm-9999.9 ohmTemperature measurement range: 0-65/32-149Operating temperature range: 0-45/32-113Voltage measurement resolution: 0.01VCurrent measurement resolution: 0.001AVoltage measurement accuracy: +/- (0.1% + 2words)Current measurement accuracy: +/- (0.2% + 4 words)Power measurement range: 0-120WRefresh rate: 0.5Hzcolour: as shownMaterial: ABSSize: 64x22x12mmPackage Contents:1 x AT35 USB TesterOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
