RANGE
Purpose Read or change the active RPT range.
Command
Query
“RANGE n:XX”
“RANGE?”
Classic “RANGE= n:XX”
“RANGE ”
Default “RANGE 3,HI”
Arguments n: ‘1’ for the low range of the selected RPT.
‘2’ for the mid range of the selected RPT.
‘3’ for the high range of the selected RPT.
XX: ‘LO’ for the low pressure RPT.
‘HI’ for the high pressure RPT or if PPC2+ has only one RPT.
Remarks The range and active RPT must be selected before making changes to settings that
are dependent on the range. Each RPTs has 3 separate ranges. You must specify
both the range and the RPT. The system MUST BE VENTED to switch RPTs. The
query reply is in the current units unless the current units are altitude units. If the
units are meters, then the range will be specified in kPa. If the units are feet, then
the range will be specified in psi.
