This is the force to keep the housing spinning slowly at a
constant speed. The force required to start the spinning initially
will be greater. This is not the correct reading. To ensure an
accurate reading the force direction must be held at 90 degrees.
(As shown). Reading is to be taken from the inner bolt pattern.
