HP Saw E4419B manual Error List then Clear Errors

Error Messages

Introduction

Errors are retrieved in a first in first out (FIFO) order. If more than 30 errors occur, the error queue overflows and the last error in the queue is replaced with error -350, “Queue Overflow”. Any time the queue overflows the most recent error is discarded.

Once the errors are read they are removed from the error queue. This opens a position at the end of the queue for a new error message, if one is subsequently detected. When all errors have been read from the queue, further error queries return +0, “No errors”.

To delete all the errors in the queue from the front panel press:

•System , More , Inputs

Error List then

Clear Errors .

To delete all the errors in the queue remotely use:

•the *CLS (clear status) command.

The error queue is also cleared when the instrument power has been switched off.
