for medium and fast, 4 wire measurements and
autorange ON.
The 8508A will also be con fi gured for
Low Current, Fast AD Integration OFF, and

9.3.4 Adjust PRS
Clicking on the Adjust PRS button will step
the operator through the PRS-300 adjustment
procedure. The procedure consists of measur-
ing all 43 internal resistors using the DMM and
storing the actual resistance values into a table.
These resistance values are used in the algorithm
to create the programmed resistance value. See
section 8.1.4 for more information.
