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).

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 N o error. After reading the error

message(s), press f1 to return to monitor mode.
