The limit test is performed after MATH operations. Unit prefixes are applied before the limit test, for
example:
Low Limit = -10.0, High limit = 10.0. A 1.5V reading passes (PASS)
Low Limit = -10.0, High limit = 10.0. A 0.6 M
reading equals 600,000 (FAIL)
Limit set #1 is available as a multiple display, which shows a bar graph and a pass/fail indication for
the measurements. While the limits bar graph is displayed, the programmed values for limit set #1
can be viewed by pressing
INFO
.
The digital output lines can be programmed to reflect the results of limit tests. The first test that fails
sets a programmable digital output pattern, where the test execution order is LOW1, HIGH1, LOW2,
HIGH2. If all tests pass, another programmable pattern is set.
