Description
These commands are used to de fi ne the digital output “ fail ” patterns for the
speci fi ed tests (0 to 7, 3-bit; 0 to 15, 4-bit). Note that the “ fail ” patterns for
Limits 2, 3, and 5-12 apply only to the grading mode.
Tests are performed in the following order:
1. Limit Test 1
2. Limit Test 2
A. Lower Limit 2
B. Upper Limit 2
3. Limit Test x, where x = 3, 5-12 in ascending numerical order.
A. Lower Limit x
B. Upper Limit x
The fi rst failure in the test sequence determines the bit pattern for the digital
output port. Subsequent failures in the test sequence will not change the
de
fi ned digital output pattern. Note that the output value can be speci fi ed as
a binary, octal, decimal, or hexadecimal value.
NOTE 16-bit I/O is available with the 2499-DIGIO option. The maximum 16-bit output
value is 65535.
