LLO (local lockout)
Use the LLO command to prevent local operation of the instrument. After the unit receives
LLO, all its front panel controls except the POWER are inoperative. In this state, pressing
the LOCAL will not restore control to the front panel. The GTL command restores control to
the front panel.
