Shuts down the instrument in the normal way (NORMal) or forced way (FORCe). In case there is
another application with modified data pending for saving, the application prompt the user. The
system waits until the user responds in the normal mode. It will go off after 20 seconds of wait in the
force mode and all data will be lost.

Lock the Front-panel keys (Remote Command Only)
Disables the instrument keyboard to prevent local input when the instrument is controlled remotely.
Annunciation showing a “K” for ‘Klock” (keyboard lock) alerts the local user that the keyboard is locked.
Klock is similar to the GPIB Local Lockout function; namely that no front-panel keys are active with the
exception of the Power Standby key. (The instrument is allowed to be turned-off if Klock is ON.) The Klock
command is used in remote control situations where Local Lockout cannot be used.
Although primary intent of Klock is to lock-out the front panel, it will lock-out externally connected
keyboards through USB. Klock has no effect on externally connected pointing devices (mice).
