Limits
Limit testing allows you to set high and low limit values. When the reading falls outside these limits,
the instrument beeps and displays the "HI" or "LO" message.
The limit values are stored in volatile memory. The values are reset to zero when the instrument is
turned off. Limits can be used with all measurements (except continuity and diode measurements).
For information on using the USB port as a status indicator for limit testing, see
Pass/fail output from
USB connector (on page C-5).
