Too many errors
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 multimeter 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?
