Transporting and Storing

1. To prepare the Gravitational Torsion Balance for transporting or storing:

Remove the front plate.

b. Raise the locking mechanism to securely anchor the pendulum bob.
c.

Check to be sure that the torsion ribbon is hanging straight down the center of the tube. If it is not,
lower the locking mechanisms, be sure the torsion wire is centered, and raise the locking mechanisms
again. Repeat as necessary until the ribbon is centered in the tube.

d. Reinstall the packing foam into the chamber to secure the pendulum bob.
e.

Replace the plate.

2. The Gravitational Torsion Balance may be stored flat in its shipping container.

3. Store in a cool, dry place, and protect the device from any jarring or rough handling.

Safety Precaution

The large masses are made of tungsten, which is not toxic. Be careful not to drop the 1.5 kg masses.
