Step 8 (Optional) Repeat Steps 1 through 7 for the 50T and 150T elements in setting groups 1, 2, and 3.
Before testing settings in other setting groups, a setting group must be selected using the
CS/CO-GROUP commands. To activate setting group 1, CS-GROUP=1 would be entered to select
setting group 1 and CO-GROUP=1 would be entered to make setting group 1 active.
Also, the pickup settings made in Step 3 (Table 13-11) must be changed to specify the setting group
being tested. To test settings in group 1, replace the 0 in the S0-x50 commands with a 1 (S1-x50).
