BNC 1201 - 6 1/2 Digit Digital Multimeter - Manual (Page 159)

160
*OPC
Sets the “operation complete” bit (bit 0) in the Standard Event register after the
command is executed.
*OPC?
Returns “1” to the output buffer after the command is executed.
*PSC {0|1}
Power-on status clear. Clear the Status Byte and Standard Event
register enable masks when power is turned on (*PSC 1). When *PSC 0
is in effect, the Status Byte and Standard Event register enable masks
are not cleared when power is turned on. [Stored in non-volatile memory]
*PSC?
Query the power-on status clear setting. Returns “0” (*PSC 0) or “1” (*PSC 1).
*SRE <enable value>
Enable bits in the Status Byte enable register.
*SRE?
Query the Status Byte enable register. The multimeter returns a
decimal value which corresponds to the binary-weighted sum of all bits
set in the register.
*STB?
Query the Status Byte summary register. The *STB? command is
similar to a serial poll but it is processed like any other instrument
command. The *STB? command returns the same result as a serial
poll but the “request service” bit (bit 6) is not cleared if a serial poll
has occurred.
