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 3-1 shows the status annunciators that may appear in the bottom line of the screen in monitor mode. Some instruments also have device-specific annunciators (see the plug-in module manual for more information).

Table 3-1. Monitor Mode Display Annunciators

Annunciator	Description
mon	The instrument is in monitor mode
bsy	The instrument is executing a command
err	An error has occurred (see “Reading Error
	Messages” below)
srq	A service request has occurred

Reading Error Messages Whenever the screen 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, type the following SCPI command (followed by the Return key):

SYST:ERR?

The error message will be displayed in the bottom line of the Text Ouput Area.

To see if another error was logged, repeat the above command by pressing

UTILS, RCL_PREV, then Return.

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