Active Limit (Upper Lower)
This key toggles the active limit line settings to the upper or lower limit.
Limit State (Off Single Segmented)
This key sets the limit line state to off, single, or segmented. See Figure: Limit Line State Menu. Limit line amplitude is stored even when turned off.
Note: Both the upper and lower limit lines for a trace must be of the same type: either both are single, or both are segmented.

Limit Alarm (On Off)
When turned on, the Limit Alarm sounds a repeating beep at the controller device (tablet or PC) when the trace touches the limit line.
Pass/Fail Msg (On Off)
When turned on, a Pass or Fail message is displayed to indicate whether the trace touches or exceeds the limit line (Fail).
Limit Preset
Turns both upper and lower limit lines off and clears limit amplitude settings. The next time a limit line is turned on, it will be displayed at its default amplitude level.
