- 1. Mode selection: you can press the key to choose among direct mode, quick charge mode and disconnected
- 2. Over-voltage and under-voltage alarm: when voltage is higher than 5.3V or is less than 4.7V, it shows the arrow to inform you of over-voltage and too-low voltage. And the arrow will not stop flashing until voltage is withing normal range.
- 3. Current zero calibration: the USB meter might have larger testing error in terms of small current due to aging components and changing environment. To deal with such case, you need to have this meter done the
- current zero calibration.
- 4. Screen rotation: long press the KEY for about 4 seconds and LED will light on, the release the KEY when LED light off, in this way, its display screen will rotate.
- 5. Screen closing: long press the KEY for about 6 seconds and release the KEY later to close the display screen.
- 6. Capacity unit switch: press the KEY for about 4 seconds and release the KEY when LED light on and later light off, then you can choose the USB meter to display capacity in mAh or mWh.
