Functions, Measuring Pulse | Tunturi F400 guide

N.B. Protect the meter from direct sunlight, as it may damage the liquid crystal display. Do not expose the meter to water or severe impacts, as these may also damage the meter.

FUNCTIONS

PULSE

Shows pulse frequency per minute (40-240 beats/min). The heart symbol beside the pulse value flashes in time with the exerciser’s heartbeat (see MEASURING PULSE).

ENERGY CONSUMPTION

Shows estimated calorie consumption in kilocalories (0-999 kcal) during workout. In theory energy consumption is calculated from pedalling resistance, speed and distance pedalled, but because different people’s capacity to produce energy (efficiency) varies, the energy consumption display shows only 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 per hour (0.00- 99.9 km/h).

DISTANCE

Shows distance in km cumulatively (0.00-99.9 km).

MEASURING PULSE

Measure the pulse as follows:

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.

N.B. The shape of the ear sensor designed by TUNTU- RI 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.

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.

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.

Sometimes 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.

Remember to clean the ear sensor. Clean the ear sensor after use, for example, with mild soapy water. Do not use solvents.

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.
