MMODE
Purpose Read or change the active measurement mode.
Command
Query
“MMODE= mode ”
“MMODE”
Classic “MMODE= mode ”
“MMODE ”
Arguments Mode: "A" Absolute mode
"G" Gauge mode
"N" Negative gauge mode
Note
Measured pressure values are returned with “g” to identify
measurement mode for both gauge and negative gauge
measurement modes.
Remarks The active RPT or an AutoRange range should selected before setting measurement mode
since measurement mode is range specific. The measurement mode can also be set using
the “UNIT” command but the “UNIT” command does not distinguish between gauge and
negative gauge while the “MMODE” does.

3.2.11
MSGFMT
Purpose Read or set the type of program command format to use (enhanced or classic).
Command
Query
“MSGFMT n
“MSGFMT?”
Classic “MSGFMT= n
“MSGFMT”
Arguments n: ‘1’ to use the enhanced command format.
‘0’ to use the classic command format.
Defaults “MSGFMT 0”
Remarks The user can select the type of remote command format to use. This format must agree with
the format sent to the PPC4.
The enhanced query form of this command (“MSGFMT? n ”) should always be used to set the
desired format, as it will be accepted regardless of the current format (classic or enhanced).
