Using System Features

Using System Configuration and Alignment Keys

•Clear Error Queue(s) - The error history queue retains and displays all errors once they have been detected, even if they are no longer detected after a period of time has elapsed. After reviewing the error queue you will likely want to clear it before making another measurement. Note that if an error condition exists continuously, the error will not appear in the queue after the error history queue has been cleared.

•Verbose - When an error is made in using the instruments programming commands, the verbose feature displays the command in which an error has been detected. An error indicator will appear in the diaplayed command line immediately following the entry that caused the error. This feature can help you troubleshoot programming problems.

You can exit the error history queue display to return to a measurement display by pressing the ESC or the Return key.
