HP 3468A - Local and Remote Operation Modes

LOCAL 9
LOCAL 901
The LOCAL 901 message clears the 3468A from the REMOTE operation mode
and reenables front panel control. Pressing the front panel LOCAL key ac-
complishes the same thing, provided the key has not been disabled by the LOCAL
LOCKOUT Message. LOCAL 9 removes every instrument on interface 9 from the
remote mode.
If the 3468A is in Remote with Local Lockout set, the only way to return to front
panel control is to either turn power off and then on again or execute the Clear
Lockout / Set Local (CL/SL) message. For many controllers this is the same as the
LOCAL command, i.e., LOCAL 9. The command LOCAL 9 takes all instruments
out of Local Lockout that are on that loop. The command LOCAL 901 would
return the 3468A to front panel control but a subsequent REMOTE command (or
OUTPUT 901) would return it to LOCAL LOCKOUT.

LOCAL LOCKOUT 9
The LOCAL LOCKOUT message locks out the 3468A‘s front panel keys, including
the LOCAL and SRQ keys. The lockout will remain in effect until it is cleared over
the interface loop by sending the LOCAL message to the multimeter or cycling the
3468A's power.
