				4. REMOTE OPERATION
UNITn
Purpose	Read or set the pressure unit of measure unit and measurement mode.
Command	“UNITn unit (, ref”)”
	“UNITn unitn (, ref”)”
	“UNITn unitg (, ref”)”
Query	“UNITn unita (, ref”)”
	“UNITn unitd (, ref”)”
	“UNITn?”
Classic	“UNITn=unit (, ref”)”
	“UNITn=unitn (, ref”)”
	“UNITn=unitg (, ref”)”
	“UNITn=unita (, ref”)”
	“UNITn=unitd (,ref”)”
	“UNITn”
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 and the HL
			Q-RPT is not active.
			Specify the HL Q-RPT if the Hi and Lo Q-RPTs are OFF
		‘2’	Specify the Lo Q-RPT if the HL Q-RPT is not active and measurement
			mode is not differential.
		‘3’	Specify the HL Q-RPT if the HL Q-RPT is active.
Arguments	Unit:	The text corresponding to the pressure unit of measure. A unit mode
		character can optionally be added to the end of the units:
		‘a’ for absolute measurement mode.
		‘g’ for gauge measurement mode.
		‘n’ for negative gauge measurement mode.
	ref:	‘d’ for differential measurement mode (Hi Q-RPT only)
		The optional unit reference temperature only if the unit is “InWa”
Remarks	This program message determines what unit of measure and what measurement mode is used to
	display pressure values. Refer to Table 13 for a detailed list of the units available and their labels.
	If the unit text is not followed by an explicit mode character (‘a’, ‘g’, ‘n’ or ‘d’) then “gauge” mode is
	assumed. There can be a space between the unit text and the ‘a’, ‘g’, ‘n’ or ‘d’.
	If the unit specified is “InWa”, an optional second argument “ref” can be set. The “ref” can be 4, 20,
	or 60 corresponding to InWa at 4 °C, 20 °C or 60 °F. If this second argument is not given when
	the unit is “InWa”, then the reference temperature is assumed to be 20 °C. This can also be added
	directly onto the end of the Unit argument if desired.
	The fifth character of the reply is always ‘a’ for absolute mode, ‘g’ for gauge/negative gauge mode
	or ‘d’ for differential mode.			White spaces precede this character if needed. The temperature
	reference is added to the reply only if the unit is “InWa”.
	The reply includes the measurement mode character in the fifth position, with an ‘a’ indicating
	absolute mode, a ‘g’ indicating gauge or negative gauge mode or a ‘d’ indicating differential mode.
	The “MODE” command can also be used to set the desired measurement mode only.
Example	Cmd sent:	“UNIT? kPaa”
(enhanced)	Query reply:	“kPaa”
	Sent:	“UNIT? InWag, 4”
	Query reply:	“inWag, 4”
	Sent:	“UNIT? InWaa60”
	Query reply:	“inWaa, 60”
Example	Cmd sent:	“UNIT psi n”
(enhanced)	Query reply:	“psi g”		(‘g’ used to indicate both gauge & neg gauge modes)
Example	Sent:	“UNIT=kPaa”
(classic)	Reply:	“kPaa”
	Sent:	“UNIT=InWag, 4”
	Reply:	“inWag, 4”
Errors	ERR# 7:	The unit is invalid.
	ERR# 6:	The ref is invalid.
	ERR# 20:	Absolute measurement mode and altitude units are not allowed with a gauge Q-RPT.

VER
Purpose	Identify the RPM4, US or SI units, the Q-RPT labels and the software version.
Query	“VER?”
Classic	“VER”
Remarks	The software version of the RPM4 can be read. This is useful for checking for the presence of the
	RPM4 and for reference purposes. It indicates the internal Q-RPT(s) and software version.
Example	Query sent:	“VER?”
(enhanced)	Query reply:	“DH INSTRUMENTS, INC RPM4 us A350K/BG15K Ver1.00 ”
Example	Query sent:	“VER?”
