How to use the tester?

Voltage and current measurement:
Insert the USB male into the 5V charger and the female into the phone and other devices to directly read the voltage and current parameters.

Measure battery capacity:
By using a linear charging circuit such as TP4056 and using this capacity meter to fully charge a completely depleted battery, the capacity reading is the battery capacity. This method can also measure the charging capacity of mobile phones and even calculate their charging efficiency.

Data reset:
Press and hold the button until (which set of data) becomes the next set of data, then release the button to automatically jump from the beginning to the next set of data.

Data viewing:
Double click the button (within 0.5S) to enter data viewing mode. The backlight indicator will flash, and then the next set of data will be displayed again. Double click to exit data viewing mode, and the backlight indicator will remain on.

Measure the quality of Micro USB cables:
When inserting devices such as mobile phones into the motherboard
MEIRIYFA USB Power Meter current and voltage tester while displaying voltage and current mAH data, easy to view can detect mobile power output mAH. multiple groups of test data save, power failure save function does not affect data transmission.
Equipped with USB port and micro USB port, convenient for testing equipment. Higher accuracy, the current parameters will not jump randomly, and the current sampling of 25 milliohms will result in smaller losses. With precise current calibration function, the current accuracy is higher.
USB 3.0 current and voltage tester with LCD display, real-time monitoring of USB power charging status, voltage, current, capacity and other indicators at a glance, power failure data memory function, test cell phones, mobile power capacity, charging head, rechargeable battery, data line and other product tools.
Data zeroing: press and hold the button until (the first group of data) into the next – group after releasing the button, automatically jump to the next – group of data from zero. If the voltage is high or low, the backlight LED will flash and the alarm will be prompted, and the LED is always on for 30S when the button is pressed.
Data view: double click the key (within 0.5S), enter the view data view mode, the backlight LED will flash, and then display the next group of data, double click to exit the data view mode, the backlight LED is long light.
