Trip odometer.
Trip Odometer
The Trip odometer allows you to keep
a record of the trip miles or kilometers
independent of the Odometer.

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 hourmeter that is always activated by an external
input so that actual engine hours can be
recorded. Quick press the push-button while

Hour-meter.
The last digit on the right blinks up and

maximum speed under normal conditions.
The maximum speed is displayed and
changes as the speed is increased over the
current maximum.
The Trip Odometer is fully user resetable.
