3.5 Accessing the user program
To configure the XDP for a specific application, it is
necessary to leave measurement mode and enter the
user program as follows (see menu maps in "Figure 14" on
page 44 and "Figure 15" on page 45 ):
While in measurement
mode, press the [ENTER],
[ENTER], [ESC], [ENTER], and
[ESC] keys in sequence.
Enter the operator-level password ( 2719 ) at the next
screen to access the menus available to the end user.
Note that a different password is required to access the
factory-level menus.
Use [

] and [

] to
position the cursor under
the desired character.
Then, use [

] and [

] to
increment the value. Press
[ENTER] when done.
This screen shows the
highest level of the user
program , which is referred
to as the main menu .
3.6 Exiting the user program
To leave the user program , proceed as follows from the
main menu:
Press the [ESC] key.
You are now back in
normal measurement
mode.
Notice that the padlock is no longer visible at the upper
right corner of the display window. Once the user program
has been accessed with a valid password, the menus at
that programming level remain unlocked when you return
to measurement mode. With the menus unlocked, you
may reenter the user program by simply pressing the
[ESC] key only. To re-lock the menus, see the instructions
in "Chapter 4. Setup" on page 19 .
NOTE: If the unit is powered down, the user program will be
locked when the unit is powered up again.
To program a specific feature of the XDP, proceed to the
appropriate section of "Chapter 4. Setup" on page 19 .
