14-6 Remote Operations 2400 Series SourceMeter
®
User’s Manual
When REM is turned off, the instrument is in the local state, and front panel oper-
ation is restored.
NOTE If LLO is in effect, LOCAL will be locked out. OUTPUT ON/OFF is still
operational in remote. If ARM:SOUR is set to manual, the TRIG key will
be active in remote.
TALK
This indicator is on when the instrument is in the talker active state.
LSTN
This indicator is on when the SourceMeter is in the listener active state.
SRQ
When this indicator is on, a service request has been generated. This indicator
stays on until the serial poll byte is read or all the conditions that caused SRQ
have been cleared. See Section 15, “Status Structure,” for more information.
LOCAL key
The LOCAL key cancels the remote state and restores local operation of the
instrument.
Pressing the LOCAL key also turns off the REM indicator and returns the display
to normal if a user-defined message was displayed.
If the LLO (Local Lockout) command is in effect, the LOCAL key is also inopera-
tive.
For safety reasons, the OUTPUT key will still be active in LLO.
