USB current and voltage tester battery capacity tester detection table digital LED display Detector
Features:
Display voltage and current mAH data for easy viewing.
It can detect mobile power output current.
Save multiple sets of test data, with power-down save function.
It does not affect the data transmission.
Higher accuracy. The current parameters will not bounce.
Takes power from USB male port and Micro USB port. Can detect Micro USB line quality
Take Current 25 milliohms as sample, smaller loss
With current calibration function, higher current accuracy
 
Parameter:
Input voltage: 3V-7V
Voltage Resolution: 0.01V
Test Current: 0.05A-3.50A
Current Resolution: 0.01A
Capacity range: 0-19999mAH
Accuracy: ± 1%
Line loss: 0.1 milliohms
Test Content: battery voltage, current, discharge capacity (total of 10 sets of data)
 
Note:
You will receive a new detector with a protective film on the screen. You can tear it before use.
Usage:
1. Measuring voltage and current: Plug USB male port into 5V charger and female port to mobile phones or other equipments, read current and voltage directly.
 
2. Battery capacity test: Charge the empty battery to full capacity and read the battery capacity directly with the detector. Like this, you can also measure charge capacity of phone,and even calculate the charging efficiency.
 
3. Measuring mobile power output capacity and efficiency: connect the mobile power with this detector, turn on the mobile power, long press the detector button until the volume data reduces to zero, then ues this mobile power to charge the phone several times until it is of no power and automatically shut down. Then ,open the detector, and the capacity displayed will be the mobile power output current.
Output mAH * Output voltage 5V / battery mAH * Battery voltage 3.7V = mobile power efficiency.
 
Data cleared:
Press and hold the button until after (the first of several sets of data) into the set and release the button to automatically skip to the next set of data from scratch.
 
View:
Quickly double click the button (0.5 Sec or less) into the data viewing mode, backlight LED flashes, and then click to display the set of data, double-click to exit viewing mode, LED backlight bright long.
 
High or low voltage alarm:
LCD and backlight LED flashes, the alarm prompt. Press the button, LED light will be bright for 30 seconds.
 
Data calibration: an electronic load device, a constant current source.
Adjust constant current source to 8.5V - 10V (recommendate 9V), set electronic load to CC mode (constant current mode), calibrate four current 3A, 2A, 1A, 0.3A respectively.
Package Included:
1 x Current Voltage Detector
