	Using a fuse coupled with one pole (-) or (+) is recommended for over-voltage protection purpose in case the car equipment is too old or the power cannot be guaranteed. It isadvisable to use fuses which have the rated current less than 2A.		Using a fuse coupled with one pole (-) or (+) is recommended for over-voltage protection purpose in case the car equipment is too old or the power cannot be guaranteed. It isadvisable to use fuses which have the rated current less than 2A.

	~~=== Installation ===~~

	~~Quick installation through 5 steps:~~

	~~# Step 1: Pierce oil tank~~
	~~# Step 2: Based on oil tank's height, cut a suitable level indicator~~
	~~# Step 3: Configure new length~~
	~~# Step 4: Install the level indicator in the oil tank~~
	~~# Step 5: Re-adjust the sensor according to the volume of the oil tank~~

	~~==== 2. Configuration software interface ====~~

	~~'''A. On mobile platform'''~~

	~~Connecting the sensor to LIGO mobile configurator~~

	~~</div>~~

	Configuring and managing the appropriate settings for the LiGO device sensor is essential to ensure its proper, stable, and accurate operation. It also allows for continuous monitoring of the device's operational status, potential failures (whether caused by the sensor itself or external factors), and overall lifespan.

	In some situations, there are oil tanks with specific dimensions, interconnected oil tanks, or oil tanks that are either too long or too large. Using just one sensor to measure the accurate fuel level inside these oil tanks may not be feasible. Hence, there is a need to connect two or more sensors together through a data processor called SUM-DATA.
