This meter displays an odometer and two trip meters.
The odometer shows the total distance traveled by the vehicle.
The two trip meters show two different distances traveled independently since each counter was last reset to zero. You can use one trip meter to calculate fuel economy and another to measure the distance for each trip. If the power supply is disconnected, all odometer data will be cancelled.
The trip counter reset button allows you to reset the two trip counters to zero, as well as change the counter readings.
To change the meter reading, quickly press and release the button. The meter display will change in order from odometer to odometer A, odometer B, then back to odometer each time the button is pressed.
To reset counter A to zero, first display counter A, then press and hold the button until the counter resets to zero. The same procedure can be used to reset meter B.
