STATus:QUEStionable:CURRent:LIMit <supply>,<value>
STATus:QUEStionable:CURRent:LIMit? <supply> [,MIN|MAX]
The STATus:QUEStionable:CURRent:LIMit sets the limit for amperage on one of the
seven supplies in the mainframe. If it is exceeded, a warning is generated. These
values are stored in non-volatile memory.
The STATus:QUEStionable:CURRent:LIMit? returns a floating number representing
the limits for amperage in the mainframe.

Power Supply Maximums:
•
This command corrects the polarity of <value> to match the specified
<supply>. It then determines if <value> is within the valid range for the
specified <supply>; if it is not, the limit is set to MAX. No error is generated.
•
Remember to execute a SYSTem:NVSave after setting all the limits you desire.
This will move them into non-volatile memory.
