Comments

• This program makes

⁄

bridge measurements on channels 0, 1, and 2 of

multiplexer card number 1. The wiring diagram used is on page 28.

• Since each strain measurement must have an unstrained reference,

the unstrained references are downloaded prior to each set of

measurements.

• The unstrained references can be stored on disk for later use.
