1 Locate the vertical standard in Box 3 and gently remove it from its case. Follow these steps:
a. Over a table or countertop, snap open the yellow clasp and spread the opened two parts of the case (see
Figure 2-32
).
b. Pick up the standard by the edges, and turn it over so that the blank is facing up.
c. Inspect the standard for dust. If dust is present, clean the standard with isopropyl alcohol and a lint-free
tissue.

2 Position the standard on the stage beneath the stylus, with the printing facing the front of the system (see
Figure 2-33

standard located to the back of the stylus tip
NOTE –
The above activity cannot damage the stylus/sensor. However, clipped data may
appear on the monitor.
3 Press the Stylus Down button to lower the stylus onto the standard (see
