pulses per mile or kilometer rounded off
to the nearest 100 th. The rightmost digit
will be a “P” to remind the operator that
they are in the “Programming” mode. The
digit changes and inputs are the same as
number 1 (Service Hours) above. Also
present is the same option to do nothing
for 32 seconds and the microprocessor
will reset itself and will change nothing.
Holding the push-button on for four
seconds while a digit is flashing will make
the microprocessor compute the
observation window and will store this
window and the pulses per mile or
kilometer rounded off to the nearest 100
pulses in the EEPROM. The display will
now show “donE” and the operator should
release the push-button to resume normal
operations.
6. The sixth menu feature “PPgn LO”
(Program Low axle) is used to program
the low speed axle pulses per mile or
kilometer.
The implementation and activation are the
same as number 5 (Program High axle)
above.
7. The next item in the menu is the input
level control for the speed pulse input. The
display will show “ InPuT “.
If nothing is done for 4 seconds then the
display will change to “L n H” and the L
will be flashing and every 4 seconds the
next letter will flash.
If the button is pressed when any selection
is flashing, that input signal level will be set
to that level.
The choices are low, normal and High. Low
is normally used for magnetic pickups and
normal and high for other types.
8. The last menu item “donE” is used to exit
from this menu.
Leaving the display in “donE” for four
seconds will cause the microprocessor to go
back to normal operations and change
nothing.
Run menu
Pressing and holding the push-button for
two seconds during normal operation will
activate the “run menu”.
The display will show “HELLO” and wait
for you to release the push-button.
When the push-button is released the first
item on the menu will be shown. In four
seconds the microprocessor will go to the
first menu feature.
