Procedure - Precor SPINNER CHRONO POWER Service Manual

An exerciser quits a workout and dismounts the bike without setting the resistance level
l
to minimum.
In this case the bike will perform an inaccurate AutoCal because the resistance was not
set to minimum. The new exerciser will read inaccurate power WATTS results unless a
new AutoCal is performed with the resistance set to minimum.

Procedure

Review entire procedure before starting.
3. Set the resistance level to minimum (resistance knob turned fully counterclockwise):
4. Start pedaling the bike at 55 rpm or greater, then slow down and allow the pedals to
stop. When the pedals and flywheel stop, the bike will perform the power measurement
AutoCall. Wait a minimum of 10 seconds for the auto-cal to complete
IMPORTANT: The resistance knob must be set to the minimum resistance level to
correctly perform the auto-cal function. The WATTS parameter will be incorrectly com-
puted if the resistance knob is not set to minimum resistance level during auto-cal.
5. Verify the measured WATTS at minimum and maximum resistance levels:
a. Set the resistance to minimum.
b. Start pedaling and maintain the speed at 60 rpm as reported on the console RPM
indicator. While continuously pedaling, verify the measured WATTS at minimum
and maximum resistance levels. Continuously pedal between measurements.

IMPORTANT: The bike must be AutoCal'd before making the WATTS meas-
urement. Also, the bike must be continuously pedaled between the min and max res-
istance WATTS measurements. If the pedals stop, a new AutoCal may occur
invalidating the measurements.
9. Verify the bike operation per and return to service.
