–330 Self-test Failed;Measurement Channel Fault
–330 Self-test Failed;Measurement Channel A Fault
–330 Self-test Failed;Measurement Channel B Fault
–330 Self-test Failed;Calibrator Fault
Refer to “Calibrator” on page 104 if you require a description of the calibrator test.
–330 Self-test Failed;ROM Check Failed
–330 Self-test Failed;RAM Check Failed
–330 Self-test Failed;Display Assy. Fault
Refer to “Display” on page 104 if you require a description of the Display test.
–350 Queue overflow
The error queue is full and another error has occurred which could not be recorded.
–361 Parity error in program
The serial port receiver has detected a parity error and consequently, data integrity
cannot be guaranteed.
–362 Framing error in program
The serial port receiver has detected a framing error and consequently, data integrity
cannot be guaranteed.
–363 Input buffer overrun
The serial port receiver has been overrun and consequently, data has been lost.
–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.
