Switching between Remote and Local Modes
When Switching from Local to Remote Mode
If this instrument receives a “
:COMMunicate:REMote ON
” command from the PC when
it is in the local mode, it switches to the remote mode.
• The REMOTE indicator is turned ON.
• All keys except the LOCAL key are disabled.
• Settings entered in local mode are retained even when this instrument switches to
remote mode.
When Switching from Remote to Local Mode
Pressing LOCAL key in remote mode puts the instrument in local mode. However, this
is void when this instrument has received a “
:COMMunicate:LOCKout ON
” command
from the PC (local lockout condition). When this instrument receives a
“
:COMMunicate:REMote OFF
” command from the PC, this instrument switches to the
local mode regardless of the local lockout condition.
• The REMOTE indicator is turned OFF.
• Key operations are enabled.
• Settings entered in remote mode are retained even when this instrument switches to
local mode.
