Fluke RPM4 manual ULn

RPM4™ OPERATION AND MAINTENANCE MANUAL

UDU

Purpose	Read or set the user defined pressure unit.
Command	“UDU label, ucoef”
Query	“UDU?”
Classic	“UDU=label, ucoef”
	“UDU”	User unit label (4 alphanumeric char maximum). It cannot be an already
	label:
		supported unit label.
	Ucoef:	“User unit conversion coefficient (units/Pa).
Default	“UDU USER,1.0”
Remarks	The user defined unit must be set up with the program message prior to remote or local
	selection.
Example	Cmd Sent:	“UDU MYUN, .001”
(enhanced)	Query reply:	“MYUN, 0.001000”		(No reply if GPIB-488)
Example	Cmd Sent:	“UDU? MYUN, .001”
(enhanced)	Query reply:	“MYUN, 0.001000”
Example	Sent:	“UDU=MYUN, .001”
(enhanced)	Reply:	“MYUN, 0.001000”

ULn
Purpose	Read or set an upper limit for the specified or active Q-RPT.
Command	“Uln limit”
Query	“Uln?”
Classic	“Uln=limit”
	“ULn”
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	“limit":	The upper limit pressure in the specified Q-RPT’s current pressure unit and
		measurement mode. If the unit is meters, this value is be interpreted in kPa. If
		the unit is feet, this value is be interpreted in psi.
Remarks	The RPM4 has an upper limit for each range and for each measurement mode (gauge, absolute, and
	differential).	If the pressure does exceed the upper limit, the pressure display flashes. This
	feature should always be used to prevent accidental over pressure of a device under test.
Example	Cmd sent:	“UL 1000”
(enhanced)	Query reply:	“1000.00 kPa a” (No reply if GPIB-488)
Example	Cmd sent:	“UL? 1000”
(enhanced)	Query reply:	“1000.00 kPa a”
Example	Sent:	“UL=1000”
(classic)	Reply:	“1000.00 kPa a”
Errors	ERR# 6:	The “limit” argument is out of range.
