STATus:QUEStionable:TEMPerature:LIMit <slot>,<value1>[,<value2>[,<value3>]]
STATus:QUEStionable:TEMPerature:LIMit? <slot>[,MIN|MAX]
The STATus:QUEStionable:TEMPerature:LIMit sets the limit, in
°
C, for
temperatures in the mainframe. If the limit is exceeded, a warning is issued. These
values are stored in non-volatile memory.
The STATus:QUEStionable:TEMPerature:LIMit? query returns an integer
representing the limit for temperatures in the specified mainframe slot.

•
There are two limits for each slot in the mainframe: the absolute limit (default
at 65) and the delta limit (default at 15 above the ambient air reading).
Normally, the delta limit predominates the actual limit point—where a warning
will sound. But as the ambient (mainframe intake air) increases, the delta limit
may pass over the absolute limit. The absolute limit will then dominate the
warning trip point. The actual limit point can be queried with the MAX
optional parameter on the
STAT:QUES:TEMP:LEV? query.
•
This command determines if <value> is within the valid range for the specified
<slot>; if it is not, the limit is set to MAX. No error is generated. Use MIN and
MAX parameters with the query to determine the maximum and minimum
temperature limits.
•
If having the temperature warning trip point tied to the ambient air is
undesirable, set the delta limits to 55. This effectively moves them out of
range.
•
Remember to execute a
SYSTem:NVSave
after setting all the limits you desire.
This will move them into non-volatile memory.
•
Refer to “Setting Enhanced Monitor Limits” on page 37 for information on
selecting and using temperature limits.
