*SRE Service Request Enable Command/Query
Type: Device Status
Description: This command sets the condition of the Service Request Enable
register to determine which event of the Status Byte
register (see
*STB) is allowed to set the MSS (Master Status Summary) bit. A "1"

Bit 6 (the Master Summary Status Bit) to be set. See details
regarding the
Status Byte register in Chapter 5.

Description: This query reads the Status Byte register. Note that the MSS
(Master Summary Status) bit instead of RQS bit is returned in Bit 6.
This bit indicates if the electronic load has at least one reason for
requesting service. *STB? does not clear the Status Byte register,
which is cleared only when subsequent action has
cleared all its set
bits. Refer to Chapter 5 for more information about this register.
