Agilent Technologies E1300B, E1301B Monitor Mode Display Annunciators, Reading Error Messages

		Monitor Mode	Monitor mode displays the status of an instrument while it is being controlled
			from remote. Monitor mode is useful for debugging programs. You can place an
			instrument in monitor mode using front panel menus, or by executing the
			DISP:MON:STAT ON command from the front panel or by remote. (Executing
			the remote DISP:MON:STAT ON command is the only way to assign the
			display/keyboard to an instrument from remote.) Pressing most front panel keys
			will automatically exit monitor mode and return to the instrument menu.
			However, you can use the left and right arrow keys in monitor mode to view long
			displays.
	Note
			Enabling monitor mode slows instrument operations. If the timing or speed of
			instrument operations is critical (such as making multimeter readings at a
			precise time interval), you should not use monitor mode.
			Table 2-8 shows the status annunciators that may appear in the bottom line of
			the display in monitor mode. Some instruments also have device-specific
			annunciators (see the plug-in module manual for more information).

Reading Error Messages
			Whenever the display is showing the err annunciator, an error has occurred for
			the instrument being monitored. You can read the error message, although
			doing so cancels monitor mode. To read an error message, press the following
			keys:

The error message will be displayed in the top line of the display. To see if another error was logged, repeat the above keystrokes or press:

After you have read all the error messages, executing the SYST:ERR? command causes the display to show: + 0 No error. After reading the error message(s), press f1 to return to monitor mode.
