Fluke RPM4 Bit 6 64 is reserved and cannot be set Remarks, Example Sent ∗RST? Enhanced Reply, Rse

4. REMOTE OPERATION

∗SRE

Purpose	Read or set the Service Request Enable Register.
Command	“∗SRE n”
Query	∗
	“ SRE?”
Default	“∗SRE 0”
Arguments	n:	’0 to 255’ This is the decimal representation of the bit(s) to enable. To allow the
		MAV and ESB bits to assert the SRQ line, the argument would be 32 + 16 = 48.
		Bit 6 (64) is reserved and cannot be set.
Remarks	The Service Request Enable Register determines which bits of the Status Byte can set the MSS
	bit of the Status Byte and request service by asserting the SRQ line of the IEEE-488 interface.
Example	Sent:	“∗SRE=48” (enables the MAV and ESB bits)
(enhanced)	Query reply:	“48” (no reply if IEEE-488)
Errors	ERR# 6:	n is not valid.
∗STB
Purpose	Read the Status Byte Register.
Command	“∗STB?”
Remarks	The Status Byte Register reflects the general status of the RPM4.		The ‘MSS’ bit state is
	represented by bit 6.
Example	Sent:	“∗STB?”
(enhanced)	Reply:	“80” (The MSS and MAV bits are set)
∗TST
Purpose	Read the power on self test status.
Query	“∗TST?””
Remarks	The RPM4 system memory stores the user settings (units, resolution) and retains them when
	the unit if OFF. On power-up, this memory is checked. If this memory is corrupted, all user
	settings are reset to default (as if the “∗RST” program message was executed), and the ∗TST
	query will return a non zero value. If the RPM4 passed the test on power-up OR if the ∗TST
	query was used at least once since the RPM4 was powered up the reply will be a ‘0’.
Example	Sent:	“∗RST?”
(enhanced)	Reply:	“1”
*RSE
Purpose	Read or set the Ready Status Enable Register.
Command	“RSE n”
Query	“RSE?”
Default	“RSE 0”
Arguments	n:	’0 to 255’ This is the decimal representation of the bit(s) to enable. To enable
		the RDY bit, the argument would be 1.
Remarks	The Ready Status Enable Register determines which bits in the Ready Status Register are
	enabled and included in the Status Byte Register (RSR bit), and can assert the SRQ line.
	The reply is in decimal numeric form.
Example	Sent:	“∗RSE=1” (enables the RDY bit)
(enhanced)	Query reply:	“1” (no reply if IEEE-488)
Errors	ERR# 6:	n is not valid.
*RSR
Purpose	Read the Ready Status Register.
Command	“RSR?”
Remarks	The Ready Status Register contents are cleared after reading.		The reply is in decimal
	numeric form.
Example	Sent:	“RSR?”
(enhanced)	Reply:	“6” (The MEAS and NRDY)
