Remote With Lockout State - Fluke 525A User Manual

Front panel operation is disabled except for the LOCAL (0 key). Pressing 0, using
RS-232 to send the command LOCAL, or IEEE-488 to send the GTL (Go To
Local) message returns the Calibrator to the local state.

Remote with Lockout State

When the Calibrator is placed in lockout, either via RS-232 LOCKOUT command,
or via the IEEE-488 message LLO, the 525A front panel controls are totally
locked out. The top line of the display changes to: REM.
To return the Calibrator to the local with lockout state, send the RS-232 LOCAL
command or the IEEE-488 GTL (Go To Local) message.
Table 4-2 summarizes the possible Operating state transitions. (For more
information on IEEE-488 GPIB messages, see "IEEE-488 Overview."
