DRAG
The Drag feature is a numerical value given to the
rate of deceleration of the flywheel. With a heavy
resistance setting, the flywheel decelerates quicker
and therefore the drag value is high. A lighter
resistance, a lower drag value.
This Drag value is calculated every stroke and used
in the algorithm to produce the rowing speed. This
Drag feature compensates for dust accumulation in
the flywheel housing and atmospeheric conditions
(Temperature, Altitude, Wind) which can affect the
rate of deceleration of the flywheel. For example, a
setting of 4 on one machine may need a setting of 5
on another to achieve the same level of resistance on
both machines. Using the drag value instead of the
resistance lever number is the best way to calibrate
each machine to be the same resistance.
This feature is more used for performance testing
where it is important that all machines are set to an
equal resistance, so that each rower is tested under
the same conditions.
To measure the drag value for a given resistance,
press the
TECH
button until the Drag is shown. Row
3 to 4 strokes continuously and the monitor will
calculate the drag for that resistance setting. Adjust
the resistance lever up or down until the desired drag
value is set.
