Fuel sensor: the AS10 capacitive fuel sensor
GPS tracker: S20/S30/S50/S70 A300/A500/A600/A700
1. Choose correct input. We suggest always use the analog input 1 (AD1) for the AS10 fuel sensor and choose the 'analogue input1' for the 'input'.
'Type" choose ’Capacitive sensor‘
2. For the Regular size fuel tank, just adding three calibration lines is ok.
first line always 0 0
Second line 2048 40
Third line 4096 80
Second line 2048 is constant, the 40 field is X/2, X is fuel tank Max capacity liters.
About third line, the 4096 is constant, the 80 field is X, is the fuel tank's Max fuel capacity volume, unit is liter. For example if the fuel tank full fuel capacity is 100 liters, put 100 replace 80.
Introduction: sensor value range is 0 to 4096, 0 is empty, 2048 is a half, 4096 is full. For regular size fuel tank, the sensor value and the fuel capacity is linear relationship.
Note: Protrack requires at least 3 calibration lines
