RANGE (PPC2+ legacy version)
Purpose
This command is included for reverse compatibility with PPC2+, and should only be
used if needed for command compatibility.
Otherwise, use “ARANGE” with PPC3 to set the desired operating range or “RANGE”
(PPC3 version) to set an RPT default range.
Read or select of one of three available predefined “Legacy” ranges for the Q-RPT(s). PPC3 does
not operate with three specific ranges (1, 2, 3) on each RPT.
In PPC3, requested RPT is AutoRanged to full scale corresponding to the the “n” prefix 3, 2 or 1
range on a PPC2 or PPC2+ RPT.
See the PPC2 or PPC2+ manual for details on the use of this command.

RANGE (PPC3 version)
Purpose Change the active range to one of the available internal or external default RPT ranges.
Read the active range full scale, pressure unit and measurement mode.
Command
Query
“RANGE Rng”
“RANGE?”
Classic “RANGE= Rng”
“RANGE ”
Default “RANGE IH”
Rng: “IH” for the internal, hi Q-RPT or utility sensor
“IL” for the internal lo Q-RPT
“X1H” for the first external RPM4, hi Q-RPT
“X1L” for the first external RPM4, lo Q-RPT
“X2H” for the second external RPM4, hi Q-RPT
“X2L” for the second external RPM4, lo Q-RPT
Remarks The active RPT must be selected before making changes to settings that are dependent on
the range. The system MUST BE VENTED to change active RPTs.
RPTs selected with this command are used with their full default pressure range. External RPTs
must be found and initialized using the “RPT” command or function key before the can be
selected
The reply indicates the active range in psi if the PPC3 is a “US” version or in kPa if the PPC3
is an “SI” version.
Used as a simple query, the active range is returned, which can be an AutoRanged range or a
default range (see “ARANGE” cmd).

3.2.5, 3.3.1, 3.3.4,
RATE
Purpose Read the next available pressure rate of change.
Query “RATE?”
Classic “RATE”
Remarks The next available pressure rate of change in the current pressure unit per second is
returned.
After receiving this program message, the PPC3 replies back with the data once a new
pressure measurement cycle is complete. This can take up to 1.5 seconds.
