A bit is set if the error -231, "Data questionable", occurs in the respective calculate
block.
6.13.19 Questionable Calibration Status Register
The EVENt register and the CONDition register contain information as to whether the
zero offset of a sensor is still valid.
The Questionable Calibration Status Register can be read by the following commands:
STATus:
QUEStionable:CALibration[:SUMMary]:CONDition?
STATus:QUEStionable:CALibration[:SUMMary][:EVENt]?
Table 6-31: Meaning of bits used in the Questionable Calibration Status Register

4 Sensor D Calibration
Zeroing of sensor D was not successful.
5 to 14 Not used
15 Bit 15 will never be used.
6.13.20 Use of Status Reporting System
For an efficient use of the status reporting system, the information it contains has to be
transferred to the controller and further processed. There are various methods which
are described in the following.
6.13.20.1 Service Request, Use of the Hierarchical Structure
Under certain conditions, the device may send a service request (SRQ) to the control-
ler. This service request usually causes an interrupt at the controller to which the con-
troller program can respond by suitable actions. As shown in figure 6-17
Overview on
structure of Status Reporting System, an SRQ will always be triggered if one or several
of the bits 2, 3, 4, 5 or 7 have been set in the Status Byte Register and enabled in the
SRE. Each of these bits combines the information from another register, from the error
queue or the output buffer. If the ENABle registers of the status registers are set
accordingly, any bit in any status register will be able to trigger an SRQ. To utilize the
