2.2.3
Arm Balancing
The arm (3) carries also a calibration weight (10), which can be turned in or out to a lim-
ited degree in order to balance the arm.
In practice, however, it is simpler to leave the arm slightly off balance in such a way that
a small initial force is exerted on the paw. This helps to retain the paw in the correct posi-
tion at the beginning of the experiment.
This slight initial force brings about a small error equivalent to an increase in the actual
force as compared with that indicated on the scale.
However, this error is constant in every measurement and every multiplication of the
scale, i.e., the addition of one or more discs does not affect the measurements and their
comparative values.
After each test, the slide should be returned to its starting position by lifting and pushing it
back to the left. Do not remove the knurled nut on the slide as, even if there are not addi-
tional discs, the calibrated weight of the slide includes the nut.
