Description
YOTINO USB Power Current Voltage Meter Tester
◆Measuring voltage and current:
USB adapter plug 5V tester, plug connected the phone and other devices, read the voltage and current parameters directly
◆Test MicroUSB cable quality:
Plug the phone and other equipment plug, first with 5V USB adapter plug tester, remember the voltage, and then use the MicroUSB cable plug connected the 5V tester plug, and remember the voltage, the smaller the voltage difference MicroUSB line quality better
◆Test battery capacity:
Use TP4056 and other linear charging circuit to charge a empty battery fully through this capacity meter, the tester readings is the capacity of the battery, can also measure cell phone charging capacity, cell phone charging efficiency can even be calculated.
◆Data clear:
Hold down the button until (group of data) into the next group release button, automatically jump to the next set of data from scratch.
◆Data view:
Quick double-click the button (within 0.5S) to enter the view data mode, the backlight LED will blink, and then press button to display the next set of data, double-click the button to exit the data view mode, the backlight LED long bright.
