C.1 Connecting the Heart rate system (option 928824)
To install a heart rate option purchased afterwards, follow the instructions given in the user
guide supplied with the ergometer. Installation of the Heart rate option itself has to be done by
service personnel only.
C.2 Using the Heart rate option
The heart rate option is automatically recognized by the ergometer. The Polar belt should be
mounted around the chest of the test subjects (at heart level) with Polar trade mark pointing
forwards from the middle of the chest. The belt should not be to loose. If you have a weak
signal, check following tips:
•
Wet the contacts on the right and left backside of the Polar belt for good contact
•
Stay near the receiver (within a range of 1 meter) which is located in the display unit
at the test subjects side below the readout.
•
Due to the integration measurement principle it can take a few seconds before the
readout on the display shows the correct value. Be patient.
•
The test subject should be positioned in such way that a straight virtual line can be
drawn between the Polar trade mark on the belt and the receiver inside the display
unit.
