mode, the unit will never enter the program mode
again. If an error was made, the unit will need to be
replaced. The serial # and the background total how-
ever are still viewable by holding the magnet on the left
target as described above.
• If the security feature is left off, tapping the left target
once more will make the display show PROG.
• PROG will be display for about 10 seconds. If a pro-
gramming error was made, tapping the left target once
more before the 10 seconds has elapsed will send the
RT1000 back to the beginning of the program mode
where the error can be corrected if need be. At this
point leaving the RT1000 untouched will allow it to
leave the programming mode and after 10 seconds
the display will show: Example: 125750.0 (or preset
value).
• If the security feature is turned on, tapping the left tar-
get once more will make the display show y n. The
unit is now asking you to confirm that you want the
security feature on. Tap the left target for YES, the
right target for NO. Tapping the left target (y) will make
the display exit the program mode and lock the unit.
The display will show: Example 125750.0 (or preset
value).
• Tapping the right target (n) will return the display to
SEC OFF.
Exiting Program Mode
• When the PROG prompt is displayed and there is no
input activity for 10 seconds, the unit will return to the
previous state prior to entering programming mode.
Normal Operation
Idle (Wheel has not been turning)
• The electronic hubodometer waits in a low power con-
sumption mode. The unit will go into active mode if
motion is detected or into programming mode if acti-
vated by a programming tool. The meter display is on
during idle mode and displays the current total. If the
meter is in idle mode for more than 1 hour the display
turns off until it is activated. To reactivate the display
after it has gone off, but before starting to turn again
touch the programming magnet to the left sensor.
Active Mode: Wheel starting to turn
• The display turns off once the wheel is turning. The
hubodometer monitors the wheel position by polling
the 2 Hall-Effect motion sensors at a sample rate that
is based on current speed of wheel.
Active Mode: Wheel stops turning
• When the meter is at rest for a minimum of 15 sec-
onds, the display is enabled and shows the total count
and measurement units. The meter will enter idle
mode and after 1 hour of no activity the display will
turn off.
