RANGE
Purpose
Change the active range to the default range of the Hi, Lo or HL Q-RPT. Replies 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 Hi Q-RPT
“IL” for the Lo Q-RPT
“HL” for the HL Q-RPT
Remarks
The active Q-RPT must be selected before making changes to settings that are dependent on the
range. Q-RPTs selected with this command are used with their full default pressure range. The reply
indicates the active range in psi if the RPM4 is a “US” version or in kPa if the RPM4 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).

RATE
n
Purpose
Read the next available pressure rate of change.
Query “RATE
n
?”
Classic “RATE
n
”
Optional Suffix
“n”
The active Q-RPT is assumed if no suffix is given.
‘1’ Specify the Hi Q-RPT if the Hi and Lo Q-RPTs are NOT OFF
Specify the HL Q-RPT if the Hi and Lo Q-RPTs are OFF
‘2’ Specify the Lo Q-RPT
‘3’ Specify the HL Q-RPT if the HL Q-RPT is active
Remarks
The next available pressure rate of change in the current pressure unit per second is returned.
After receiving this program message, the RPM4 replies back with the data once a new pressure
measurement cycle is complete. This can take up to the current read rate period (1.2 seconds
by default).
