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.

Press System, More (1 of 3), Show System to access the two-page show system display. The first page shows firmware and option information (see Figure 2-1). Press More (2 of 3) to access the second page, which shows option and hardware status information (see Figure 2-2).

Under the Show System menu is a key that enables you to enter a password, and four information-only keys, in a lighter font, that show the serial number, model designation, firmware revision, and host ID for your instrument.

NOTE		Diagnostics features require a service password. The password is only
		available if the service guide has been purchased. All service diagnostic
		features are described in the service guide.
