Calibrating the DigiRoller
You will need to recalibrate the DigiRoller if you:
■ change the wheel size
■ change the batteries (if you’re using a 2-ft wheel).
After changing the batteries, the unit resets the wheel circum-
ference size to 4 feet (the default size). You must reprogram
the unit to accept a different wheel circumference size so that
it will measure correctly.
1) Turn the unit on. Press the [Rcl] key and then press the
[RESET] and [+D] keys at the same time. You will see the
following*:
*NOTE: If you are in Metric Mode or have meters selected as
the current units of measurement, the display will
show approximately 1.22 meters.
2) Repeatedly press the [+D] key until the display shows the
desired wheel size. The unit will display the 2-foot, 3-foot
and 4-foot settings (note that we currently only provide
wheels with 2- & 4-foot circumferences).
3) Press the [RESET] key to clear the display and return the
unit to the measuring mode.
