b. You must replace the Setup_num parameter with number of the VFP setup memory that sets
"Open All" (no connection) condition.
c. You must replace the Setup_num parameter with number of the VFP setup memory to use
for C measurement.
d. In Load_vfp_data subprogram, enter your VFP data file name instead of "VFP_FILE". Your
