 Even if the Timing Belt is flipped, the LCD screen may not
change at all. In this case, flip the Timing Belt again after a few
seconds have passed.

If measurement results differ greatly from each other, acoustic
sounds may not be picked up properly in any of the
measurements. Therefore, flip the Timing Belt again with the
tweezers, and record the value at which two measurement
results are approximate. Displaying errors in the range 1/100 to
5/100, the Measuring Tool has high reliability.
