Detail description
Odometer
The commercial speedometer contains an
odometer to maintain a record of the total
mileage and trip mileage. During normal
operations and after a power on the
odometer display shows;
This display cannot be reset. A quick press
of the push-button changes the display to
the Trip odometer.
Trip Odometer
The Trip odometer allows you to keep a
record of the trip miles or kilometers
independent of the Odometer.
The Trip Odometer is fully user resetable.
While in the Trip Odometer display press
the push-button for 4 seconds and the Trip
odometer is reset to zero.
The speedometer is capable of switching
between two different speed axles, selected
by inputting a high or low level on an input
pin.
The pointer travels over a 270-degree dial to
indicate mph (or kph) indicates the speed.
The kph is handled the same as a mph in
the microprocessor. The pulses per mile
will be pulses per kilometer and the self-cal
will be for 1 kilometer instead of 1 mile.
There is no provision to change from miles
to kilometers.
Hour-meter
The speedometer also contains an hour-
meter that is always activated by an external
input so that actual engine hours can be
recorded. Quick press the push-button while
in the Trip Odometer function displays the
Hour-meter.
