Heart Rate Indicator; Meaning Of % Grade - CYBEX 770T Owner's Manual

Heart Rate Indicator

Contact Heart Rate — Lightly hold hand grips on the handlebar ensuring that hands are clean and
contact both the front and back sensors of each grip. A heart rate will display in typically 30 seconds
or less.
Factors that interfere with heart rate signal:
hand lotions
•
oils or body powder
•
excessive dirt
•
Wireless Heart Rate — To use this feature, a Polar® compatible heart rate transmitter belt (not
included) must be worn.
Once the actual heart rate is determined, the LED is blinking to the displayed BPM and the Heart LED lights
up. The color of the light represents a scale of low to high target heart rate.

Meaning of % Grade

A 1% grade is not the same as a 1 degree incline. The % grade is the relationship of the
measurement of rise over the measurement of run (also called slope). For example, a 1 foot (meter)
rise in height over a length of 100 feet (meters) is a 1% grade. Expressed as a mathematical formula,
the grade is calculated as follows: 1 ft. (m) / 100 ft. (m) = 0.01 = 1%
With respect to treadmills, the percent grade is roughly equal to the increase in height (rise) of the
treadmill divided by the length (run) of the treadmill.
The degree of incline can be related to % grade by taking the Arctangent of the grade. For instance,
15% grade is equal to 8.53 Degrees (ArcTan(.15)=8.53º). The opposite is true to determine % Grade
from Degree of incline (Tan (8.53º)=.15).
