9.2.1.8 STATus:QUEStionable register
This register contains information on ambiguous device states. They can
occur, for example if the device is operated outside its specification range. It
can be queried using the commands STATus:QUEStionable:CONDition? or
STATus:QUEStionable[:EVENt]?.
Not all bits of this register are free for any use. Table 9 shows what bits have
requirements.

Bit
No.
Meaning
2 BATTery low
This bit is set if the supply (or battery) voltage becomes too low.
4 TEMPerature
This bit is set if the internal temperature is too high.
9.2.2 Use of the Status Reporting System
In order to be able to effectively use the status reporting system, the
information contained there has to be transmitted to the host where it is further
processed. There are several methods which are described in the following
sub-sections.
9.2.2.1 Service request, making use of the hierarchy structure
Under certain circumstances, the device can send a "service request" (SRQ)
to the host. As Section 0 shows, an SRQ is always initiated if one or several
of the bits 0, 1, 2, 3, 4, 5 or 7 of the status byte are set and enabled in the
SRE. Each of these bits combines the information of a further register, the
error queue or the output buffer. By setting the ENABle sections of the status
registers correspondingly, it can be achieved that any bits in any status
register initiate an SRQ. In order to use the service request, some bits should
