Calibrating the Altitude Automatically
Select Settings > Features > Altitude > AutoCalib > On / Off
By using the altitude Automatic Calibration option, you can adjust the starting elevation to be set
always the same in the beginning of the exercise. Calibrate the elevation manually and turn the
Automatic Calibration (AutoCalib) on. From now on, this elevation will be always used as the base
elevation in the beginning or the exercise, when automatic altitude calibration is in use. Also, if the
Automatic Calibration is turned on and you calibrate the cycling computer manually, this new value
will be used as a new starting elevation for the Automatic Calibration option.
If the elevation or air pressure changes significantly, you are prompted to confirm the change. If you
change the elevation,Altitude calibrated to xx m/ft indicates that calibration has succeeded. If Altitude
calibration failed is displayed, re-calibrate the altitude.
You can also set the elevation for the Automatic Calibration also by using the Polar ProTrainer 5
software. For more information see software help.
Select this option if you train in the same environment. This way, altitude values are always correct.If the
sport profile of the exercise includes automatic calibration, altitude measurement always begins at this
elevation regardless of the general elevation settings.
Recording Rate
The cycling computer records the training data in 5 second intervals by default. You can set a new
recording rate in Settings > Features > Rec.rate > 1 / 2 / 5 / 15 / 60 sec.
The cycling computer can store your heart rate, speed, cadence, power and altitude in 1, 2, 5, 15 or
60 second intervals. A longer interval gives you more recording time, while a shorter interval allows you
to record more heart and other data. This enables accurate data analysis using the Polar ProTrainer 5
software.
A shorter recording rate consumes the memory of the cycling computer more rapidly. The remaining
recording time is displayed on the lower row when setting the rate. Default recording rate is 5 seconds.
When less than 30 minutes of maximum recording time is left, the recording rate changes
automatically to longer recording time (1s > 2s > 5s > 15s > 60s). This will maximize recoding time to
record exercise data. When the session ends, the current recording rate will be used in the next
training session.
The following table shows the maximum recording times for each recording rate. The maximum
recording time can be shorter, if you record a large number of short exercises.
Recording rate will change when less than 30 minutes of recording time is left. Memory low is displayed 60
minutes before the memory runs out.
