No professional wiring, easy to use, as long asPlug inUSB port, discharge charge, you can monitor the work of equipmentCurrentVoltage, and statistical battery capacity.

The new machine screen surface affixed to the protective film, if you do not need to tear up   Can be used as a daily simple test tool   1. Can detect, flat, mobile phone battery charging capacity, to determine how much battery performance, whether the need to replace. 2. Can detect the discharge capacity of the charging treasure, calculate the conversion rate of the charging treasure. 3. You can detect the charging current of your digital device. 4. 5V router and any other 5V USB port devices (such as USB lights) operating current and so on   Comes with usb input line, there are microusb mouth, you can use other lines input. One by one power / mobile power, pay attention to the default use of usb interface, that is, 5v; the other end of the load, you can phone. parameter:   Input voltage:3V-7V   Voltage resolution:0.01V   Test current:0.05 A-3.50A   Current resolution:0.01A   Capacity range:0-19999mAH   Accuracy:Plus or minus 1%   Line loss:0.1 oh or so   Test content:Battery voltage, current, discharge capacity(A total of 10 sets of data)           Measured voltage and current:   USB male plug in the 5V charger, the mother inserted the phone and other equipment, read the voltage and current parameters directly   Measured MicroUSB line quality:   The mother of the phone and other equipment, first with the machine male plug 5V charger, remember the voltage, and then MicroUSB line from the 5V charger into the machine MicroUSB hole to remember the voltage, the smaller the voltage difference MicroUSB line quality better   Measuring battery capacity:   The use of TP4056 and other linear charging circuit through the capacity of the battery completely charged to the battery is fully charged, the capacity of the reading capacity for the battery capacity, the use of this method can also measure the phone charging capacity, and even calculate the phone charging efficiency   Measurement of mobile power output capacity and efficiency:   First connect the machine to the mobile power, turn on the mobile power, press the button until the capacity data is zero, insert the phone several times until the mobile power is turned off automatically. 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   Data cleared:   Press and hold the button until the (group of data) becomes the next group and release the button to automatically jump to the next set of data from zero.   Data View:   Quickly double-click the button (within 0.5S), enter the view data view mode, the backlight LED will flash, and then show the next set of data, double-click to exit the data view mode, backlight LED long light.   High voltage or low alarm:   LCD screen arrow, backlight LED will flash, alarm tips. Press the button LED to illuminate 30S.   Power on:   Through the MicroUSB or cable USB male power, the LCD screen shows the contents of all 1S (detection of the LCD screen is intact), and then display the last data (capacity, and the first few sets of data), the current voltage, current and voltage Or low tips.   Data calibration function settings:An electronic load meter, a constant current source.   The constant current source is set to 8.5V and above 10V (recommended 9V), the electronic load is set to CC mode (constant current mode) 3A, 2A, 1A, 0.3A four current calibration. The following are the same as the "   Take 3A as an example:   3A calibration: the electronic load set constant current mode 3A, the thermometer LCD screen current will automatically slowly calibrate (10S or so) can see the LCD screen current will change, after calibration off the electronic load data automatically protected.
