5.
Remove the Specimen Mount.
While holding the rotate shaft, rotate the
Specimen Mount counter-clockwise until it is completely free of the rotate
shaft.
NOTE:
If the specimen mount only rotates but does not unscrew, remove the
cover from the PIPS II cabinet and manually restrain the timing pulley at the
bottom of the Whisperlok to prevent it from rotating while the specimen
mount is being unscrewed.
6.
Install the new Specimen mount.
If necessary, install the XY stage parts.
7.
Replace the Top Cover plate and Viewing Port.
8.
Close the Vent valve and turn on the power.
9.
Verify that the stage home position is correct.
If the stage home
position is not correct, calibrate it as described below.
a)
Lower the stage and set the home position. Alignment > Home.
b)
Observe the actual rotational position of the stage. It will not be at
the home position. Note how many degrees in rotation it is from
the proper home position.
c)
Adjust the home calibration setting to compensate. Maintenance >
Calibration > Stage. The calibration setting is in 10ths of a degree,
so that if the position is 10 degrees away from the proper position
adjust the calibration setting by 100.
d)
Repeat this process until the home position is correct.
