-410 Query INTERRUPTED

A command was received which sends data to the output buffer, but the

output buffer contained data from a previous command (the previous

data is not overwritten). The output buffer is cleared when power has

been off, or after *RST (reset) command has been executed.

-420 Query UNTERMINATED

The power meter was addressed to talk (that is, to send data over the

interface) but a command has not been received which sends data to the

output buffer. For example you may have executed a CONFigure

command (which does not generate data) and then attempted to read

data from the remote interface.

-430 Query DEADLOCKED

A command was received which generates too much data to ﬁt in the

output buffer and the input buffer is also full. Command execution

continues but data is lost.

-440 Query UNTERMINATED after indeﬁnite response

The *IDN? command must be the last query command within a

command string.
