STEP 5. Entering Thickness of Load Standard
Enter the thickness of the PTFE load standard supplied with the 16453A test fixture by
following these steps. The thickness is printed on the surface of the case. When you use a
user-defined load standard for measuring dielectric materials, enter its thickness.
NOTE
The thickness value written on the case is a typical value. If you need to enter a highly
accurate value, measure it with a micrometer or calipers.
