Limit
The limit test function enables you to perform pass or fail testing to upper 
and lower limits that you specify. You can set the upper and lower limits 
to any value between 0 and ±120% of the highest range for the present 
measurement function. The upper limit value you select must be larger 
than the lower limit value. The initial factory settings for both values is 
zero.
Enabling the limit operation
Press  Shift > Limit to enable the limit operation.
The Limit annunciator is illuminated and the limit function is enabled.
• This math operation applies to all measurement functions except 
continuity and diode test.
• The instrument clears all limits after a Factory Reset (
*RST command) 
or an Instrument Preset (SYSTem:PRESet command), or when a 
measurement function is changed.
