Function characteristics
1) 8192 pixels HD display;
2) D+ D- Voltage Tester
3) Memory power time data such as power;
4) The single monitoring shows charging voltage, current, power, power WH, mAH, charging time and other information;
5) USB is the copper pin and low resistance in sampling technology, access after almost does not affect the charging speed;
6) Wide voltage from 3.60 V to 32.5 V;
7) Low and lower power since the
8. When the power is > 0.5W, the time will be calculated!
Important Tips
1) Backlight default time is 10S time, through the key button, switch to the BL interface:10S time interface, double-click or three-click to increase(+) time or decrease(-) time the backlight time, and the same time backlight switch inchBL:OFF(time) ~BL:ON( time) 1S ~ 59S rangeinch Increase(+) or three-Click(-) after the reduction, then long press key is a continuous increase in the reduction.To meet the individual needs of users.
BL:10S→ USB tester default backlight time is 10S, 10S automatically turn off screen brightness
BL:ON→USB tester backlight is on, always on
BL:OFF→USB tester backlight is off, there is no backlight
3) When the ambient temperature changes or the outside heat conduction to tester causes the current to not return to zero and the display shows 0.01A or 0.02A or otherwise, Please Hold on the key button then insert to USB Charger It can make the current temperature of the ambient current zero calibration, After the zero can more accurate measurements. And when in Zero calibration, the output cannot have any load current consumption, so USB tester display 0.00A
