Introduction - Polar Electro LOOK Kéo Power User Manual

ENGLISH

2. INTRODUCTION

Together with a Polar cycling computer (CS600X,
CS600 and CS500), Polar LOOK Kéo Power
system provides the following training information:
• Actual, average and maximum power values
• Left/Right Balance (CS600X and CS600 only)
• Cycling cadence
• Cycling efficiency (CS600X and CS600 only)
For information on the power features of your
cycling computer, refer to the user manual of the
cycling computer in question.
The latest versions of the user manuals can be
downloaded at www.polar.fi/support and

4 Introduction
For video tutorials of the Polar LOOK Kéo Power,
go to www.polar.fi/en/support/video_tutorials or
www.lookcycle.com.
The power output measurement of the Polar LOOK
Kéo Power system is based on strain gauges.
There are eight strain gauges attached to each
pedal axle. Each pedal axle has two measuring
circuits, and each circuit has four strain gauges.
The force applied to the pedals bends the axle
slightly, and causes the strain gauges to lengthen
or shorten. This leads to a change in the
resistance of the gauges. By measuring the change
in resistance, the force applied to each pedal can
be determined, and the power output generated
while cycling can be measured. Cycling cadence is
measured with a magnet located in the pedal.
