-350 Queue overflow
The error queue is full because more than 20 errors have
occurred. No additional errors are stored until you remove errors
from the queue. The error queue is cleared when power has been
off, or after a
*CLS (clear status) command has been executed.
-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 a
*RST (reset)
command has been executed.
-420 Query UNTERMINATED
The meter was addressed to talk (i.e., 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 an
ENTER statement 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 all data is lost.
-440 Query UNTERMINATED after indefinite response
The
*IDN? command must be the last query command within a
command string. Example:
*IDN?;:SYST:VERS?
501 Isolator UART framing error
502 Isolator UART overrun error
