STATus:QUEStionable Register
This register contains information about different states which can occur. It can be read
using the commands
STATus:QUEStionable:CONDition?
and
STATus:QUEStionable[:EVENt]?
.

Bit No.
Meaning
0
Voltage
This bit is set while the instrument is in constant current mode (CC). The voltage is regula-
ted and the current is constant.
1
Current
This bit is set while the instrument is in constant voltage mode (CV). The current is variable
and the voltage is constant.
2 to 3
Not used
4
Temperature overrange
This bit is set if an over temperature occurs.
5 to 8
Not used
9
OVP Tripped
This bit is set if the over voltage protection has tripped.
10
Fuse Tripped
This bit is set if the fuse protection has tripped.

Query of an instrument status
Each part of any status register can be read using queries.
There are two types of commands:
●
The common commands
*ESR?
,
*IDN?
,
*STB?
query the higher-level registers.
●
The commands of the
STATus
system query the SCPI registers
(
STATus:QUEStionable
)
The returned value is always a decimal number that represents the bit pattern of the
queried register. This number is evaluated by the controller program.
