5.0 USING THE ADM-880C AIRDATA MULTIMETER
5.1 KEYPAD
These instructions will be easier to follow if you have the meter in front of you as you are reading. You will be able to press
the keys and observe the results as you work your way through the instructions. Sections 5.2 ALT KEY through Section
5.9 MODE KEY, describe the use of each meter key in detail, beginning with the ALT key in the upper left of the keypad,
working across the bottom of the keypad to the READ key on the lower right, up to the STORE key on the upper right and
then across to the MODE key on the left side of the keypad. Pressing the ALT key twice at any time serves as an ESCAPE
key, causing the meter to exit a keypad option and return to the previous settings. Pressing ALT / ALT does not affect the
memory contents. This ESCAPE function is very useful if the user has begun making selection loop changes and is
interrupted. The user can press ALT / ALT and begin again.

5.1.2 KEYPAD FUNCTIONS
The primary function on a key is shown in large type and is accessed by pressing the key. Some keys, such as the MODE
key, have multiple options within the primary function loop. The primary function on the MODE key is used to select a
measurement mode from the options available: differential pressure, absolute pressure, temperature, air flow, pitot tube
velocity, AirFoil velocity or VelGrid velocity. Scroll through the options within any primary function loop by pressing the
function key repeatedly.
The secondary function loop is accessed by pressing the ALT key, followed by a specific function key, such as the MODE
key, which allows access to the secondary function for that key. The secondary function for the MODE key is the TIMED
READ mode. The options within a secondary function loop may be selected by pressing the READ/SELECT key if the
displayed prompt is followed by a small letter “s”, or may be scrolled through by pressing the specific function key, such as
the MODE key, repeatedly. These instructions will use the convention that “press ALT / MODE” means “press the ALT key,
then press the MODE key”.
The tertiary (third level) function loop is accessed by pressing ALT, followed by a specific function key such as the MODE
key, then ALT again, then the specific function key again (ALT / MODE / ALT / MODE). The tertiary function for the MODE
key is CONFIGURE. The options within the tertiary function loop may need to be selected by pressing the READ/SELECT
key, if the displayed prompt is followed by a small letter “s”, or may be scrolled through by pressing the specific function key,
such as the MODE key, repeatedly.
The numerical entry functions shown on certain keys are only accessible when required to enter a number, such as using
the “GO TO” function to find a particular reading in memory, or configuring the date or time.
Keypad functions are outlined on the following page.
