Remote/Local
In local mode, the electronic load is controlled from
the front panel but will also execute commands sent
over the GPIB. The electronic load powers up in
local mode and remains there until it receives a
command over the GPIB. Once the electronic load is
in remote mode,
REMOTE will be shown on the front
panel LCD, all front panel keys except LOCAL are
disabled. Pressing LOCAL key on the front panel
will return to local mode. Local can be disabled
using local lockout, so only the controller or the power
switch can return to local mode.
