Equilibrium Adjuster for Dial Reading
The balance is brought to perfect equilibrium quickly
by means of the crank at the right of the case. The zero of the vernier
is then made coincident with the the dial. The vernier movement is controlled
by a small knob at the right of, and near the top of the case. This is
done quickly while the beam is swinging and the case closed, resulting
in a great saving of time, and saving the agate knife edges.
Equilibrium Adjuster for Analytical
This device, which is standard equipment on all Becker
Analytical Rider Balances, makes use of a chain to obtain equilibrium without
using the adjusting nut at the end of the beam. The hook carrying the chain
can be made to move up or down by means of the thumb screw on the top (outside)
of the case, until equilibrium is obtained. This is done while the beam
is swinging and the case closed, resulting in a great saving of time, and
saving the agate edges.
