CALCulate:LIMit

:MODE?

:LOWer? <mode>

:UPPer? <mode>

Description:

Query the mode or the value of

the Limit function.

Parameter:

<mode>: The value of mode is

from 01 to 25.

Response:

Return <NR1> format string.

Example:

CALC:LIM:MODE? ; Query the mode of the
Limit function.
CALC:LIM:UPP? 07 ; Query the upper value
of the mode 7.

Note:

CALCulate:LIMit:MODE? Query will

respond with an error if meter is not in limit
function and if the state of limit function is
disabled. To set meter to limit function, use the
CALCulate:FUNCtion command.
