Miscellaneous Commands
Table 4 lists the miscellaneous commands that control general
housekeeping functions of the Digital Multimeter.
Table 4: Miscellaneous Commands
*IDN?
Returns instrument identification.
*OPC
Reports when operation is completed by
setting the Operation Complete bit in SESR.
*OPC?
Reports when operation is completed. Same as
*OPC except returns a 1 to the output queue
and dose not set the SESR bit.
*RST
Resets the protection levels and states, resets
the current and voltage levels to zero, sets the
output off, and sets memory section to 00.
*WAI
Wait to continue. This command forces
sequential operation of commands. This
command is required by IEEE-488.1-1987.
The DMM, however, forces sequential
operation of commands by design.
:SYSTem:ERRor?
Read the next item from the error/event queue.
:SYSTem:VERSion?
Returns the SCPI version level.

Standard Event Status Register.
Syntax:
*CLS
Examples:
*CLS clears all event registers.
*ESE
Function:
Set or return the bits in the Event Status Enable Register (ESER). The
ESER enables the Standard Event Status Register (SESR) to be
summarized on bit 5 (ESB) of the Status Byte Register (SBR).
Syntax:
*ESE <NR1>
*ESE?
<NR1> is in the range from 0 through 255.
Returns:
<NR1> is a number from 0 to 255 that indicates the decimal value of the
binary bits of the ESER.
