UnLocking
Repeat the Locking procedure twice for unlocking.
MASTER LOCKING
The indicator facilitates locking all the PAGES (except Operator PAGE) by applying Master Lock Code. Under Locking, the
parameters are available for
view only
and cannot be adjusted. The Master Lock, however does not lock the operator
parameters. This feature allows protecting the rather less frequently used parameters against any inadvertent changes while
making the frequently used operator parameters still available for any editing.
For enabling / disabling the Lock, step through the following sequence:
Locking
1. Press and release PAGE key while the indicator is in the MAIN Display Mode. The Lower Readout shows PAGE and the
Upper Readout shows 0.
2. Use UP / DOWN keys to set the Page Number to 123 on the Upper Readout.
3. Press and release ENTER key. The indicator returns to the MAIN Display Mode with the Lock enabled.
The Figure 3.2 below illustrates the Locking procedure.
