Fluke RPM4 manual ‘state’, AUTOZEROn=RUN

RPM4™ OPERATION AND MAINTENANCE MANUAL

ATM

Purpose	Reads the next measured pressure from RPM4’s on-board barometer (if present).
Query	“ATM?”
Classic	“ATM”
Remarks	The atmospheric pressure as measured by the RPM4 on-board barometer is returned in
	the current pressure units of the active Q-RPT (always absolute). This measurement is
	followed by the units text. Not all RPM4s are equipped with an on-board barometer.
Example	Query sent:		“ATM?”
(enhanced)	Query reply:		“97.12348 kPa a”
Example	Sent:		“ATM”
(classic)	Reply:		“97.12384 kPa a”
Errors	ERR# 23:		RPM4 is not equipped with a barometer.
See Also	3.5.7.1
AUTOZEROn
Purpose	Read or set the status of the AutoZ function.
Command	“AUTOZEROn state”
Query	“AUTOZEROn?”
Classic	“AUTOZEROn= state”
	“AUTOZEROn”
Default	“AUTOZERO1”
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
Arguments	‘state’:		’0’	Autozero OFF
			’1’	Autozero ON
Remarks	The RPM4 AutoZ function can be turned ON and OFF. There is a separate AutoZ flag for
	the gauge, absolute, and differential measurement modes for each Q-RPT. This
	command sets the AutoZ status for the current mode of the specified or the active Q-RPT
	only. To set the sate of AutoZ for a measurement mode, you must be in that mode.
Example	Cmd sent:		“AUTOZERO 0”
(enhanced)	Query reply:		“0”	(No reply if GPIB-488)
Example	Sent:		“AUTOZERO=0”
(classic)	Query reply:		“AUTOZERO=0”
Errors	ERR# 7:		The argument was other than ‘0’ or ‘1’.
	ERR# 10:		The suffix is invalid.
See Also	“ZOFFSET”, “MMODE”
	3.5.1
AUTOZEROn=RUN
Purpose	Run the AutoZero routine.
Command	“AUTOZEROn RUN (,Pref)”
Query	“AUTOZEROn? RUN (,Pref)”
Classic	“AUTOZEROn= RUN (,Pref)”
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
Arguments	‘Pref’: The AutoZ reference pressure in Pa. Optional when the RPM4 is not in
		absolute measurement mode, as the reference is usually “0”.
Remarks	The RPM4 AutoZ function can be remotely run with this command only if AutoZero is
	ON. You should ensure that the pressure is stable for valid determination of Zoffset. If in
	differential mode, the previous 5 measurements of the Q-RPTs are averaged for Zoffset
	calculation so you should ensure that the RPM4 has been stable for at least 5
	measurement cycles before running a remote AutoZ in differential mode.
Example	Cmd sent:		“AUTOZERO RUN”
(enhanced)	Query reply:		“OK”	(No reply if GPIB-488)
Example	Cmd sent:		“AUTOZERO? RUN, 97283” (abs AutoZero to 97283 Paa)
(enhanced)	Query reply:		“OK”
Example	Sent:		“AUTOZERO=RUN”
(classic)	Query reply:		“OK”
Errors	ERR# 6:		An argument was not given for the AutoZ reference in absolute mode.
	ERR# 10:		Invalid suffix
	ERR# 53		AutoZero is currently OFF.
