 White ordinary edition,










 COLOR2  
 Only the detector does not contain the load! Black high-pressure version,














COLOR3      
Only the detector does not contain the load! Black four generations

白色为普通版，支持电压测量范围为3~12V，高于9.99V无法显示十位数，适合10V以内使用；

黑色为高压版，支持电压测量范围为3~15V，15V以内均可正常显示，适合15V以内使用。

两者仅仅是支持电压不同，其他所有功能完全一致。
White for the ordinary version, support voltage measurement range of 3 ~ 12V, higher than 9.99V can not display tens of digits, suitable for use within 10V;

Black for the high-pressure version, support voltage measurement range of 3 ~ 15V, 15V or less can be normal display, suitable for use within 15V.

3.1、测电压电流：

USB公头插上USB充电器，母座插手机等设备，直接读出电压电流参数。

3.2、测MicroUSB线质量：

母座插手机等设备，先用本机公头插USB充电器，记住电压，再用MicroUSB线从USB充电器插到本机MicroUSB孔内记住电压，电压差距越小MicroUSB线质量越好。

3, Features:

3.1, measuring the voltage and current:

USB plug in the USB charger, plug the mother cell phone and other equipment, direct readout voltage and current parameters.

3.2, measuring MicroUSB line quality:

Plug the phone and other equipment, the first plug the USB plug with the machine, remember the voltage, and then MicroUSB line from the USB charger into the MicroUSB hole to remember the voltage of the machine, the smaller the voltage difference MicroUSB line the better the quality .

3.3, measuring mobile power output capacity and efficiency:

First connect the mobile power supply, open the mobile power supply, long press the button until the capacity data to zero, insert the mobile phone to charge many times until the mobile power no power automatic shutdown. The next time you turn on the unit, the display capacity is the mAH of the mobile power output. Note that this mAH is much smaller than the nominal mAH and outputs mAH * Output Voltage 5V / Battery mAH * Battery Voltage 3.7V = Mobile Power Efficiency.



3.4, the data switch:

Click the button to switch to the next set of data, double-click the button to switch to the previous set of data.

3.5, the data is cleared:

Press and hold the button for more than 3 seconds to clear the group data.

4, application examples:



4.1, test mobile phones, tablet, mobile power, etc. with the charging voltage and current:

USB plug inserted in the USB plug charger, plug the mother cell phone, tablet, mobile power and other equipment, direct readout voltage and current parameters.

4.2、测试电源、移动电源的输出电压和电流（必须配合负载器）：

检测仪USB公头插上USB充电器，母座插USB负载器，直接读出电压电流参数。
4.2, the test power supply, mobile power output voltage and current (must be with the loader):

4.4、测试移动电源的输出容量（必须配合负载器。注意“输出”两个字，这里测试的不是移动电源标称的容量，移动电源标称的容量都是指里面的电池总容量，是比实际输出容量大得多的！不懂的客户请自行搜索）：

把移动电源完全充满电，检测仪USB公头插在移动电源上，母座插上USB负载器并调至1A档，一直放电到移动电源自动关机（一定要注意负载器的散热！），这时记录的mAh数据即为移动电源的输出容量。

由于时间限制，店主并没有做详细测试，引用了一个淘友的测试图片：

一个移动电源装三节三星2600mAh电池（总容量为7800mAh），用EBD放电结果为6108mAh，用该USB检测仪检测结果为6117mah，证明该检测仪的容量测试是相当准确的！
4.4, test the mobile power output capacity (must meet the load device. Note "output" word, here is not the mobile power nominal capacity, mobile power nominal capacity refers to the inside of the battery capacity, The actual output capacity is much greater! Do not understand the customer, please search):

The mobile power is fully charged, the detector USB plug inserted in the mobile power, the mother plug in the USB loader and transferred to 1A files, has been discharged to the mobile power automatically shut down (be sure to pay attention to the heat load!), Which , The mAh data recorded is the output capacity of the mobile power supply.

Due to time constraints, the owner did not do a detailed test, a reference to a friend of Amoy test pictures:

A mobile power supply three Samsung 2600mAh battery (total capacity of 7800mAh), with EBD discharge results for the 6108mAh, with the USB detector test results for the 6117mah, prove that the detector capacity test is quite accurate!
