Limit Testing
The limit test operation enables you to perform pass/fail testing to
upper and lower limits that you specify.
Applies to all measurement functions, except continuity and diode tests.
• You can set the upper and lower limits to any value between 0 and
±120% of the highest range, for the present function. The upper limit
selected should always be a more positive number than the lower
limit. The default upper and lower limits are both “0”.
• The upper and lower limits are stored in volatile memory; the
multimeter sets both limits to “0” when power has been off, after a
remote interface reset, or after a function change.
• You can configure the multimeter to generate a service request (SRQ)
on the first occurrence of a failed reading. See “The SCPI Status
Model,” starting on page 134 for more information.
• Front-Panel Operation: The multimeter displays “OK” for each
reading that is within the specified limits. It displays “
HI” or “LO” for
each reading that exceeds the upper or lower limit. The multimeter
beeps once (if the front-panel beeper is enabled) on the first
occurrence of a failed reading after a good reading. See also “Beeper
Control,” on page 88.
5: LIMIT TEST (MATH MENU) enable or disable limit test
6: HIGH LIMIT (MATH MENU) set the upper limit
7: LOW LIMIT (MATH MENU) set the lower limit
You can also turn off limit test by selecting a different math operation
from the front panel (only one math operation can be enabled at a time).
