Subtotal mileage display

The subtotal odometer displays total mileage after reset subtotal mileage last time or the battery
power failure. The range is from 0km to 999.9km. The value of the subtotal mileage is only stored
in RAM. If the supplying power is failure (not the ignition supply power but battery supply
power), the value of the subtotal mileage will be reset to zero.

When the subtotal mileage reaches the maximum value, the numerical value will automatically
return to zero, and it can return to zero through a Disp key at any time.

–

Displaying range of subtotal mileage should be 0.0-999.9km.

–

Not display Max.height “0” except for 0.0-0.9 km

–

Update interval of subtotal mileage LED display is 0.1km, and the update frequency will not

TIME

The average speed algorithm shall meet:

–

The status of ignition switch will not affect the calculation of average vehicle speed. After the
ignition switch is turned off, average vehicle speed will not be cleared automatically.

–

Average speed can be calculated only when the oil consumption pulse signal is effective.

– After pressing reset button (not less than 1.5s), average vehicle speed should be cleared

(meanwhile, it will be automatically cleared during traveling condition).

–

When average speed is cleared, the traveling mileage must also be cleared.

Actual service life

After the vehicle drives for 500 meters, display. According to the fuel oil quantity retaining in the
oil tank and the fuel consumption in the past, estimate the running mileage.

–

Update frequency of display of possible mileage produced by residual oil in oil tank will be
once 5s (Range_Refresh)

–

When connecting to the battery for the first time or after reset, it should display “---km” until
the instrument begins to calculate average oil consumption.

–

After the vehicle travels 500m, available mileage will be shown on the screen. When residual
oil in oil tank can make the vehicle travel less than 50km (Fuel_Range_Warning), it should
display “—km”.

It is as shown in fig when the vehicle runs within 500 meters or the driving mileage is smaller than
50 kilometers.

TIME

Average fuel consumption

The average fuel consumption is calculated based on the driven distance and the total amount fuel
consumed at the time of rotating the engine. After fueling up at every turn, automatically reset the
display value.

NL11-3018b

TIME

The instrument shall calculate the average fuel consumption according to the fuel injection pulse
signal output by the engine management module and the speed pulse signal output by the speed
sensor.

–

Average oil consumption will be displayed within the range of 0.1-99.9 L/100km.
