D+ Voltage : 0.000V ~ 2.999 V Resolution precision: 0.001 V

D- Voltage : 0.000V ~ 2.999 V Resolution precision: 0.001 V

Load impedance: 0 ~ 999 ohm Resolution precision: 1 ohm

Power metering range: 0 ~ 299.999 W Resolution precision: 0.001 W

Timing maximum time: 999 H 59 M 59 S Resolution precision: 1 S

Time to refresh: > 500 ms/time > 500 ms/times

Measurement rate: 0.5 times/s

Use large equipment of the same metal manganese bronze sampling resistor

(1.0 mm diameter metal manganese bronze material 0.5W, the time will be calculated!

Important Tips:

1)Backlit the default value is 10 seconds automatically shut down, if you need to close a backlight or normally open backlighting, please in double-click backlit screen button or click the button to adjust, thank you!

2)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 buttion 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 can not have any load current consumption, so usb tester display 0.00A

2. LCD Screen Backlight:White/Blue/Black/Orange 4 kind of Backlit Optional

3. 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 “BL: OFF(time) ~BL: ON(time)1S ~ 59S range” 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

1. Why does the USB tester show 0.01A or other current when the load is not connected?

A: 1. This situation shows that the 0.01A temperature drift may be caused by the temperature drift current, make sure the USB tester is not connected to any load, and then press the button in the main interface 7 times, you can calibrate the current 0.00A!

2. Why does the USB tester show 0.01A or other current when connected to a load?

A: 1. Our USB test instrument using software calibration technology, in the case of no power, press and hold the USB tester’s key, insert the USB charger, enter the USB tester background, shows 0.00A, long press the key , The screen appears “RESET” to restore the factory settings!

3. How to set the backlight?

A: The general factory settings, set the backlight is turned on is 10s Time, please click the button to switch to the BL: ON interface, press the button for three click consecutive strikes (-) or double-click (+) to set the backlight, there are three modes to choose from, you can set the BL : ON (backlight open), BL: OFF (backlight off), BL: 1S-59S (set the 1S-59S automatically turn off the backlight time)

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
