Energetics E-204 Instruction Manual page 9

Measurement via hand pulse sensors: Sensors to record heart rate from the palms are located on the
handlebars . For recording to take place both palms have to be in contact with the sensors simultaneously [1] .
Measurement via chest strap (optional): Heart rate measurement takes place through sensors integrated in
the chest strap . There is a wireless signal to a receiver in the computer . The chest strap has to be worn correctly and
the sensors may need to be moistened [2] . This measurement is constant and accurate .
All commonly used analog chest straps, with a frequency of 5 KHz can be used .
Polar T34 is specific made for home exercise equipment . The frequency range is 4" (132 cm) . T34 is usually only
sold together with the product .
Polar T31 & T31C are sold individually and offer a frequency range of 3"
(99 cm) . Both models, coded and uncoded, will work with the ENERGETICS specific equipment .
Polar H1 set is also a standard coded transmitter and runs with 5 KHz .

Hand pulse sensor record the variation in resistance which is created by the pulsation
of the blood flowing through the palms. Movement on the hand grips, friction,
moisture and perspiration will influence the transmission. There are among people
appreciable physiological differences in the characteristics of the resistance change. For some
people the resistance is to weak to even be measured. In this case the computer will show
no heart rate.
All these factors influence the measurement, which makes it imprecise and it should only be
used for orientation.
If the hands are dry at the beginning of the workout the hand pulse sensors might not pick
up a signal at all or register a faulty one. Usually it is sufficient to moisten the palms to
correct this.

Electromagnetic influence factors
All electronic devises such as T. V., computer etc. are surrounded by electromagnetic fields or
respectively use wireless transmission like a cordless telephone. The receiver in the computer
can only conditionally differentiate between a "good" and a "bad" signal. Interfering signals
from another source can disturb the recording of the heart rate. Your exercise equipment
should be placed as far away from these interfering devices as possible.
Both measurement methods are not fit for medical purposes!
If you wear a pacemaker please check with your physician if a chest strap should
be used.
!
Important information to determine your correct and optimal heart rate as well as the heart
rates proper application during the workout can be found under www.energetics.eu and the
ENERGETICS App.
If both methods are used simultaneously, that is wear the chest strap and place the palms on
the sensors on the handlebars the values coming from the chest strap are recorded.
Not all available chest straps are compatible with the E-204. If in doubt check with your local
dealer.
