Stroke Rate Calculation
You may calculate stroke rate based on one, two or three stroke cycles. Since we are not interested in
MPH/KPH, we will disregard those indicators.
Following the instructions in the “Enter Distance” section, please enter the following values for their
respective stroke cycles:
One (1) stroke cycle . . . please enter 0.017
Two (2) stroke cycles . . . please enter 0.034
Three (3) stroke cycles . . . please enter 0.050
To measure stroke rate, simply START the timer by pressing “A” at the beginning of the cycle and STOP
the timer by pressing “A” again at the completion of the cycle. The number displayed in the upper row of
the display is the
Stroke Cycle Rate per Minute
.
Take as many readings as necessary. The
Average and Fastest
rates can be displayed by pressing “F”.
