~~10.~~ Hold down “Key 1 for more than 8 seconds and release it to enter input state of total fuel tank height. F030 in the figure below means that total height of the fuel tank is 30cm. Press “Key 2” to increase and press “Key 3” to decrease. Hold down “key 1” for 8 second to confirm the parameters.

−

~~12.2.~~ If the display screen displays 000.0 or the displayed height is quite different from the actual condition, the probe may be moved slightly or grind the fuel tank wall more. In addition, the buzzer in the equipment sounds continuously (if the buzzer sounds on and off or does not sound, it needs to seek the installation point or grind the fuel tank wall more until the buzzer does not sound).
