Appendix
Magnet Positioning
This section applies to earlier models of the SGSM.
It may be necessary to reposition the magnet in the SGSM Drive Assembly.
1.
Remove the Drive Assembly from the test cell.
2.
Turn the Drive Assembly upside down.
3.
Unscrew the support.
4. Locate the set screw that holds the magnet on the bob shaft. Loosen the
set screw enough for the magnet to move freely.
5.
Adjust the magnet so that the top is 3.16 inches from the base of the
Drive Assembly. Use calipers to measure the distance.
6. When the magnet is in position, tighten the set screw to hold it in place.
7.
Screw the support back onto the base of the Drive Assembly.
