The Festnight KWS-MX18 USB Tester is a digital LCD display device that can measure voltage, current, power, timing, and other parameters. It has a button for navigating through different sets of charging data and can also rotate the screen for easier viewing. The device is made of ABS material and is available in white or black. It has a wide range of measurements, including current, voltage, timing, power, capacity, inner temperature, and more. It is important to note that if the output voltage exceeds the allowable range, the device should not be used. The package includes one USB Test Meter.

Directions for use:
1: Click the button to view 1-9 sets of charging data.
2: Long press the button for 3 seconds to remove a set of charging data.
3: Double-click the button to rotate the screen to view.
4. Long press the button and insert the USB interface to enter the voltage calibration:
For example:
(1) If display (5.526V?) Then double click button quickly
(2) If display(5.528V?), then you can click the button to increase the display voltage.
(3) Double click button quickly, if display(5.528V?),then you can click the button to decrease the display voltage.
