Figure 8-3
Operation model for limit test
NOTE Display messages indicate which test or tests have failed, but they do not indi-
cate which limit (HI or LO) has failed. When using remote operation, you can
determine which limit failed by reading the measurement event register. See Ref
B for the FAIL? commands in Table 8-2.
Relative (Rel), mX+b, m/X+b, and log can be used with limit testing. The tests
will be done on the result of the math operation (not the input values). These
math operations are covered in Section 5.
