Technical Functions
Press the TECH button to access these features. The Technical information is displayed in the bottom left hand field
on the display.
Drive ratio
The drive ratio is a ratio of drive time to recovery time. The drive phase is always measured as 1. For example if the
drive time was 1 second and the recovery time was 3 second the drive ratio would be displayed as 1:3.0. If the drive
time is 0.7 secs and the recovery time was 2.8 secs the drive ratio would be displayed as 1:4.0.
Stroke Length
Stroke Length is a numerical value given to the length of the drive phase of the rowing stroke. The measurement is
based on the amount of flywheel revolutions from the beginning to the finish of the stroke and converted into a number
for easy reference. The numerical value is a reference number only. It does not represent a length in centimeters or
inches or an arc length but is very useful for setting a target length you wish to reach.
Average Strokes Per Minute
This feature displays the average strokes per minute from the commencement of a Just Row or programmed workout.
Heart Rate
The OTM is compatible with the Polar brand of heart rate chest belts and receivers. The Polar HR receiver plugs into
the port at the rear of the monitor.
When the OTM is receiving the signal the Heart icon will flash on and off.
The receiver must be set within 3 feet of the chest belt worn by the rower to be within range of the signal.
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.
Other Features
The OTM uses the advanced self calibration algorithm to give consistent scores across all resistance settings. This
allows scores to be comparable from machine to machine.
To save on battery life the monitor has a time out function set at 3 minutes after the last button action, rowing stroke or
completed workout.
