*ESR? returns the value of the Standard Event Status Register. The register is
then cleared (all bits 0).
Comments
– Executable when Initiated: Yes
– Coupled Command: No
– *RST Condition: none

*IDN?
*IDN?
returns identification information for the E1412A C-size multimeter. The
response consists of four fields:
HEWLETT-PACKARD,E1412A,0,A.0x.0x-A.0x.0x
The first two fields identify this instrument as model number E1412A
manufactured by Keysight Technologies (but listed as Hewlett-Packard). The
third field is 0 since the serial number of the multimeter is unknown to the
firmware. The last field indicates the revision level of the inguard-outguard
firmware.

*OPC
*OPC causes the E1412A to wait for all pending operations to complete after
which the Operation Complete bit (bit 0) in the Standard Event Status Register is
set. The
*OPC suspends any other activity on the bus until the multimeter
completes all commands sent to it prior to the *OPC command.
The firmware revision field will change whenever the firmware is
revised. A.01.00-A.01.00 is the initial revision. The first two digits
indicate the major revision number and increment when
functional changes are made. The last two digits indicate the
functional improvement level.
