MMODEn
Purpose
Read or change the active measurement mode.
Command
Query
“MMODEn mode”
“MMODEn?”
Classic “MMODEn=mode”
“MMODEn ”
Optional Suffix
“n”
The active Q-RPT is assumed if no suffix is given.
‘1’ Specify the Hi Q-RPT
‘2’ Specify the Lo Q-RPT
Arguments
Mode:
"A" Absolute
mode
"G" Gauge
mode
Measured pressure values are returned with “g” to identify measurement
mode for both gauge and negative gauge measurement modes. Differential mode
restricts access to settings on the Lo Q-RPT.
Remarks
The measurement mode can also be set using the “UNIT” command but the “UNIT” command
does not distinguish between gauge and negative gauge in it’s reply, while the “MMODE”
does. Measurement mode is range specific.

ERR# 53:
Invalid argument text.
Abs mode only with altitude units or gauge mode only with gauge Q-RPT.
The suffix indicating the Q-RPT is invalid for the current conditions.
Absolute or negative gauge mode not available with gauge Q-RPT.
Absolute Q-RPT with an absolute and negative gauge OFF calibration.
The current range cannot support gauge mode.
Gauge mode range would be negative.
Lo Q-RPT not suitable for differential mode.

MSGFMT
Purpose
Read or set the type of program command format to use (enhanced or classic).
Command
Query
“MSGFMT mode
“MSGFMT?”
Classic “MSGFMT= mode
“MSGFMT”
Arguments
mode:
‘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 RPM4
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).
It is recommended to use the “L2” and “L3” commands instead of this command for new designs.
Example
(enhanced)
Cmd sent:
Query reply:
“MSGFMT 1”
“1”
(No reply if IEEE-488)
Example
(enhanced)
Cmd sent:
Query reply:
“MSGFMT? 1”
“1”
Example
(classic)
Sent:
Reply:
“MSGFMT=1”
“MSGFMT=1”
Errors
ERR# 6:
Missing or improper program message argument(s).
