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 )

Specifications:
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
