to lock the touch screen. After the touch screen is locked, a lock icon

appears in the status area at the lower-right of the screen. You can long press

again to disable the touch lock.

You can also send SCPI commands to lock the display or front-panel keys.

:SYSTem:KLOCk:STATe {ON|OFF|0|1} /*Enables or disables the remote lock mode.*/

:SYSTem:TLOCk? /*Queries whether the remote lock is enabled.*/

In remote lock mode, all front-panel keys are disabled except for the output on/off

keys

, all output on/off key , and the power switch key . At this point, you

can press the output on/off key only to disable channel output.
