UNIT UT658B Usage:

Place the device on a charger or mobile power supply and see if the output voltage is within range. If not, please stop using it immediately. When the voltage is higher than 5.30V or lower than 4.70V (USB is 5V), a warning indicator will appear.

After confirming the output voltage is normal, users can chrge a device by plugging the charging cable into the device.

Short press the button to select one of ten sets for data recording. Press the button for 1.5 seconds to delete the current record.

If necessary, users can replace different charging cables for charging. Observe the displayed current of the USB tester and select the most suitable charging cable (the higher the current, the better the quality.
