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).
The front panel ‘Local’ key (Cancel/Esc) has no effect if Klock is ON.
