FUNCTIONS
PULSE
Shows pulse frequency per minute (40-240).
ENERGY CONSUMPTION
Shows estimated calorie consumption in kilocalories
(0-999) during workout. In theory energy consumption is
calculated from pedalling resistance, speed and distance
pedalled, but because people's capacity to produce energy
varies, the energy consumption display shows an
approximation of the real consumption. This meter calculates
the energy consumption on the basis of average values.
TIME
Shows time counted upwards in minutes and seconds
(0:00-99:59).
SPEED
Shows the speed you are pedalling at in km/h (0.00-99.9).
DISTANCE
Shows distance in km cumulatively (0.00-99.9).
MEASURING PULSE
Exercise within different pulse ranges affects the body in
different ways. For example, exercise of long duration within
a pulse range that is about 50-60 % of the maximum pulse
helps you to lose weight, whereas exercise in a range that is
about 70-80 % of the maximum develops the heart and
respiratory system and overall endurance, i.e. improves
your condition. If you don't know your maximum pulse rate,
you can use the following formulae as a guideline:
WOMEN: 226 - AGE, MEN: 220 - AGE
However, it is advisable to make sure by consulting your
doctor.
For example, to lose weight, a 50-year-old man should
exercise at a resistance and pedalling speed that raise his
pulse to about 85-105 beats/min.
MEASUREMENT WITH AN EAR SENSOR
1. Fit the ear sensor wire plug into the connecting point
on the bottom of the meter.
2. Attach the ear sensor to the earlobe where pulse is
to be measured.
3. Attach the sensor wire e.g. to the collar with the
clip provided. This will prevent moving of the
sensor and insure a more accurate reading of the
pulse. Make sure also that the wire between the
earlobe and the clip is not too long or short so that
the sensor will stay firmly in place.
NOTE! The shape of the ear sensor designed by Tunturi
makes it possible also to measure pulse on inside surface
of the ear if, for example, circulation is poor in the earlobe,
the earlobe is too small or cartilaginous as a result of
piercing.
4. The heart symbol beside the pulse value flashes in
time with the user's heartbeat.
NOTE WHEN MEASURING YOUR PULSE
If the sensor does not immediately start measuring your
pulse, or if the earlobe is cold, rub the earlobe with the
fingers to speed up circulation. Physiological differences
between different people may also cause disturbances in
pulse measurement. In these cases, try measuring on the
inside surface of the ear or on the tip of your finger.
If measuring disturbances appear while pedalling, test the
functioning of the sensor while stationary. Strong,
unintentional swaying while pedalling may also disturb
measurement. If pulse values rise above 150 beats/min.,
earlobe measurement may be affected by the speeding up
of circulation.
A strong light source, e.g. a fluorescent tube, in the immediate
vicinity of the user may cause disturbances in pulse
measurement. In this case, test the functioning of the sensor
by turning the ear sensor the other way round on the
earlobe. Pulse reading can also be affected, if the battery
power of the meter is too low.
Clean the ear sensor after use, for example, with mild soapy
water. Do not use solvents.
TELEMETRIC MEASUREMENT
More reliable pulse measurement is achieved with a
telemetric device, in which the electrodes of the transmitter
fastened to the chest transmit the pulses from the heart to
the meter by means of an electromagnetic field. This device
has a built in pulse receiver which is compatible with a Polar
telemetric pulse transmitter, sold as an optional extra.
If you want to measure your pulse this way during your
workout, moisten the grooved electrodes on the transmitter
belt with saliva or water. Fasten the transmitter just below
the chest with the elastic belt, firmly enough so that the
electrodes remain in contact with the skin while pedalling,
but not so tight that normal breathing is prevented. The
heart symbol beside the pulse value flashes in time with the
user's heartbeat.
If you wear the transmitter and belt over a light shirt, moisten
the shirt slightly at the points where the electrodes touch the
shirt.
