Using the LIMITS Menu Keys
Note that Math and Limits menus are not available for Voltage Peaks measurements.
Overview of Limits Menus
The menu items under the Limits keys allow you to:
• select the desired upper and lower measurement limits (UPPR:, LOWR:).
• 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).
