IEEE 488.2 Common Command Quick Reference

The table below lists, by functional group, the IEEE 488.2 Common (*) Commands that can be executed by the HP E1312A B-size and HP E1412A C-size 6½-Digit Multimeters. However, commands are listed alphabetically in the following reference. Examples are shown in the reference when the command has parameters or returns a non-trivial response; otherwise, the command string is as shown in the table. For additional information, refer to IEEE Standard 488.2-1987.

Category	Command	Title	Description


System Data	*IDN?	Identification	Returns the identification string of the B- or C-size
			multimeter which includes the latest inguard and
			outguard firmware versions.
			HEWLETT-PACKARD,E1312A,0,A.0x.0x-A.0x.0x
			HEWLETT-PACKARD,E1412A,0,A.0x.0x-A.0x.0x

Internal	*RST	Reset	Resets the multimeter to:
Operations			FUNC:VOLT:DC,
			VOLT:RANG 300V,
			VOLT:RES 1 mV,
			RANGE:AUTO ON,
			NPLC 10,
			ZERO:AUTO ON,
			INP:IMP:AUTO OFF,
			TRIG COUN 1,
			TRIG:DELAY:AUTO ON,
			TRIG:SOUR IMM,
			SAMP:COUN 1.
			OUTP:TTLT<n>:STAT OFF

Internal	*TST?	Self-Test	Returns “0” if self-test passes. Returns “1” if self-test
Operations			fails. Use SYST:ERR? to retrieve the error from the
			multimeter. See “Self-Test Errors” beginning on
			page 189 for a complete list of error numbers and their
			description. Return multimeter to Hewlett-Packard for
			repair if repair is required.

Synchronization	*OPC	Operation Complete	Operation Complete Command
	*OPC?	Operation Complete Query	Operation Complete Query
	*WAI	Wait to Complete	Wait-to-Continue Command

Status and Event	*CLS	Clear Status	Clear Status Command
	*ESE <unmask>	Event Status Enable	Standard Event Status Enable Command
	*ESE?	Event Status Enable Query	Standard Event Status Enable Query
	*ESR?	Event Status Register Query	Standard Event Status Register Query
	*SRE <unmask>	Service Request Enable	Service Request Enable Command
	*SRE?	Service Request Enable Query	Service Request Enable Query
	*STB?	Read Status Byte Query	Read Status Byte Query

Bus Operation	*TRG	Bus Trigger	When the multimeter is in the wait-for-trigger state and
			the trigger source is TRIGger:SOURce BUS, use
			*TRG to trigger the multimeter.
