allows access to a single menu item, you are not able to scroll to the item
which would normally appear next in the menus.
Direct Entry
In addition to the menu system, you can also access value entries, selection codes, and
commands by direct entry. Direct entry is a short cut that bypasses the menu structure.
After setup is complete, direct entry can be useful for executing often used commands,
changing certain data entry values, or performing diagnostics.
Caution should be used when using direct entry codes to enter or change parameter values.
When changing or entering a value for a given menu item, the associated values must also
be changed or input (for example, the required tank dimensions are dependent on the tank
shape selected when setting up a volume measurement). The menus provide a step-by step
process to ensure that all required parameter values are entered. When using direct entry,
the user must know which associated values must also be modified or set.
To use direct entry, you must know the item identifier, also called the keyboard code. You
can find the keyboard code for a particular menu item while using the menus as follows:
1. Scroll to the menu item of interest.
2. For all menu items except decimal number entries (floating point entries such as
0.000), simply press the period, “•”, key.
3. For decimal or floating point number entries, press the period, “•”, key followed
by the ↑ key. (The ↑ key indicates that you are not entering a decimal number,
rather you want to see the direct entry code.)
Items with 6–digit identifiers are data entry values. Items with 1, 2, or 3 digit identifiers
are commands or action items (see Chapter 7).
Example: Finding a Keyboard Code
While you are setting up the primary measurement, (as discussed in Chapter 3), when you
reach the following menu item, press the period “•” key.
Allow display of ALL
units. Change to:
Metric or English→
NEXT↓
The information screen shown below will be displayed. Since the “Allow display of
All/Metric/English units” item is not a decimal entry, it is not necessary to press the ↑
following the period “•” key.
