Use large equipment of the same metal manganese bronze sampling resistor
 (1.0 mm diameter metal manganese bronze material < 0.05R)
Product size: 65 x 24 x 14 mm
Since the power flow: < 0.003 A   (    <  3mA  )
Working temperature:  - 10 ~ + 60 ℃
Working humidity: 10 ~ 80 (no doubt)
The pressure of work: 80 ~ 106 kpa
Cumulative capacity range: 0-99999 mah precision: 0.001 Ah (New features or D+ D-   Voltage )
Item size:65 * 24 * 14 mm
Net weight: 19g
Package weight: 28g
Color: Black
Display Color: white or   black
Packing content:
1 x Digital USB Voltmeter Tester
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 a 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 < 0.003 A (  <  3mA  )
3.60V~32.5V / 0.00A~5.10A / 0 ~ 299.999W / 0 ~ 999999 WH / 0 ~ 999999 mAH / 0℃~+80℃ / 0~999 ohm / 999H 59M 59S / D+ D- Voltage 0.000V ~ 2.999 V / Since the power flow: < 0.003 A 
8.When the power is > 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

Important Tips:

1. Products Shell Color:Transparent or Blue Color Optional

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

4.When the power is > 0.5W, the time will be calculated!

​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
