VER
Purpose Identify the PPC4, US or SI units, the Q-RPT labels and the software version.
Query “VER?”
Classic “VER”
Remarks The software version of the PPC4 can be read. This is useful for checking for the presence
of the PPC4 and for reference purposes. It indicates the internal Q-RPT(s) and software version.

ZOFFSETn
Purpose Read or set the AutoZ pressure offsets (P
offset
) for the specified or active RPT (preferred
method).
Command
Query
“ZOFFSET n GaOffset , AbsOffset ”
“ZOFFSET n ?”
Classic “ZOFFSET n = GaOffset , AbsOffset”
“ZOFFSET n ”
Defaults
“ZOFFSET n = 0.0 Pa, 0.0 Pa” (Gauge Q-RPT)
“ZOFFSET n = 101325 Pa, 0.0 Pa” (Absolute Q-RPT)
Optional Suffix “n” The active RPT is assumed if no suffix is given.
‘1’ Specify the Hi Q-RPT.
‘2’ Specify the Lo Q-RPT
Arguments GaOffset
AbsOffset:
The RPT pressure offset (“Poffset”) for Gauge measurement mode (Pa).
The RPT pressure offset for absolute measurement mode (Pa)
Remarks The pressure offset (P
offset
) for the specified internal RPT (IH or IL) or the active Q-RPT can
be accessed with this program message. There is a separate offset for gauge and absolute
measurement modes, but not all modes apply in all cases. (Gauge RPTs do not support
“
AbsOffset) .

Caution
•
Using this program message overwrites the current offset.
•
Changes made using this program message take effect immediately. If no
suffix is given and the active RPT is in an external RPM4, then the P
offset
for
that RPM4’s Q-RPT will be accessed.
