Local lockout
You can use the front-panel EXIT (LOCAL) key to cancel remote operation and return control to the
front panel. However, this key can be locked-out to prevent a test from being interrupted. When
locked, this key becomes a NO-OP (no operation). Configure the following attribute to lock or unlock
the EXIT (LOCAL) key:
display.locallockout =
lockout
Where
lockout
is set to one of the following values:
0
or
display.UNLOCK
1
or
display.LOCK
For example, to lock out the EXIT (LOCAL) key:
display.locallockout = display.LOCK
Load test menu
The LOAD TEST menu lists tests (USER, FACTORY, and SCRIPTS) that can be run from the front
panel. Factory tests are preloaded and saved in nonvolatile memory at the factory. They are available
in the FACTORY TESTS submenu. Named scripts that have been loaded into the run-time
environment can be selected from the SCRIPTS submenu. Refer to
(on page 6-3) for
additional information.
User tests
User tests can be added to or deleted from the USER TESTS submenu.
