Types of limits
As shown in Figure 12-1, there are 11 limit tests that can be performed on a DUT.
These limits include:
• Limit 1: compliance test
• Limit 2: course limits
• Limits 3, 5-12: fine limits
NOTE Limit 4 is reserved for the contact check option. See Appendix F for
details.
A test is only performed if it is enabled. Thus, you can perform one, two, or all 11
tests. The tests are always performed in the order shown in the drawing.

Pass/fail information
Pass/fail information for limit tests can be obtained as follows:
• A PASS or FAIL indication on the front panel display.
• By programming the unit to output specific pass/fail bit patterns on the Digital I/
O port, which can be used to control other equipment such as a device handler
