Bit No. Meaning
2 Query error
This bit is set if the controller wants to read data from the instrument without having sent a
query. It is also set if the controller does not fetch requested data and sends new instructions to
the instrument instead. The cause is often a query which is faulty and hence cannot be execu-
ted.
3 Device-dependent error
This bit is set if a device-dependent error occurs. An error message with a number between
-300 and -399 or a positive error number, which denotes the error in greater detail, is entered
into the error queue.
4 Execution error
This bit is set if a received command is syntactically correct but cannot be performed for other
reasons. An error message with a number between -200 and -300, which denotes the error in
greater detail, is entered into the error queue.
5 Command error
This bit is set if a command is received, which is undefined or syntactically incorrect. An error
message with a number between -100 and -200, which denotes the error in greater detail, is
entered into the error queue.
6 User request
This bit is set when the instrument is switched over to manual control.
7 Power on (supply voltage on)
This bit is set when you turn on the instrument.
