(approximately 1/16-inch) when contacting the Force Transducer
Assembly (adjust the height of the drive mechanism, as
necessary) as shown in Figure D.2.

Step 5 Prior to proceeding with the displacement test, the operator
needs to become familiar with the test method. Table D.1
provides the approximate displacement locations to test. When
the TEST/READY switch is pressed and released, the drive
mechanism will begin incrementing (moving) into the
displacement gauge. The 921A displacement value is presented
on the unit display. The drive mechanism is incremented until
the displacement reaches 0.2000 inch (standard .0001 inch lead
screw) or until the TEST/READY switch is pressed and held in.
The drive mechanism will remain stationary as long as the
TEST/READY switch is held in (actuated). By monitoring the
displacement value on the unit display and pressing/holding the
TEST/READY switch, the operator can stop the platform at the
approximate displacement points listed in Table D.1 and
compare the unit displayed displacement to that of the fixture
gauge.
