1. CALIBRATING THE WHEEL SIZE

You must calibrate the wheel size of your bike before you can use your Polar Protrainer XT Heart Rate Monitor to measure distance and speed. The wheel size must be set in millimetres.

Polar Protrainer XT allows you to set in two wheel sizes (WHL1 / WHL2). Use this function if you have two bikes. The wheel size which is displayed when you leave the wheel size setting mode, will be used next time you start exercising.

TO FIND OUT THE WHEEL SIZE OF YOUR BIKE YOU HAVE THE FOLLOWING ALTERNATIVES:

METHOD 1. The quick way.

Check the wheel diameter (in inches) which is printed on the front bike wheel. On the chart below, find your wheel diameter in inches on the left and match it with the wheel size in millimetres on the right.

a tape measure around the outside of the wheel.

 

 

 

 

 

 

 

 

If you measure in inches, convert the value to millimetres

 

 

 

 

 

 

 

 

by multiplying the number of inches by 25.4 mm.

Subtract 4 mm to account for your weight on the bike.

METHOD 3. The most accurate way.

For this method ask your friend to assist you. First, mark the tread of your front tire with a line. Match this line with a line drawn on the ground. Sit on your bike and have your friend walk you forward for one complete wheel rotation. Draw another line on the ground exactly where the mark on the tire touches the ground. Measure the distance between the two lines on the ground to get your wheel circumference. If you measure in inches, convert to millimetres by multiplying the number of inches by 25.4 mm.
