Overview of Limits Menus

LIMITS
The menu items under the Limits keys allow you to:
Uppr &
Lower
• select the desired upper and lower measurement limits (UPPR:,
Limit
LOWR:).
Modes
• disable or enable Limit Testing (LIM TEST: OFF or ON)—Note that
the Limit Testing is automatically enabled when you set the upper
and lower limits, or update any menu item in the Limit Modes menu;
thus, the primary function of the LIM TEST menu item is to allow you
to turn Limit Testing off.
• set the Counter to stop making measurements when a measurement
exceeds the user-entered limits (ON FAIL: STOP). (Stop on limits
does not have any effect if the Counter is in the single measurement
mode.)
• enable the Counter to continue taking measurements after a
measurement exceeds the user-entered limits (ON FAIL: GO ON).
• change the Counter display from numeric to analog graph to quickly
visualize changes in the signal (or to quickly see when measurements
are in or out of limits) (SHOW: NUMBER or GRAPH).
