If the user selects the MODE field they will be able to
change the mode the zone is in. If the user

selects the ACT ZONE field, the current zone being
sampled can be changed.
The user can toggle the zone mode (in the
MODE
field) by pressing the right arrow key to activate the
field and using the “.” and “ — ” keys to select between
NORMAL , HOLD , and SERVICE . If the zone is set
to HOLD mode, the zone is continuously sampled.
Press the down or up arrow key to go back to the
STATUS OPTION screen. Your changes are saved
and data written upon scrolling back to the STATUS
OPTION screen.
To display DIAGNOSTICS: (diagnostic zone

data), press the right arrow key and press 3 . Press the
down arrow key twice. The first screen in a series of
seven displays:
11.5.3. DIAGNOSTICS Screen 1:
Sensor Data Register
• PRESS is the current absolute manifold

pressure in PSIA along with the output voltage
of the pressure sensor. This value should

always be 0.2 to 1.0 PSIA below ambient.
• P VOLT is pressure sensor output voltage.
• VAC P is the current absolute manifold

pressure in PSIA along with the output voltage
of the pressure sensor. This value should

always be 0.2 to 1.0 PSIA below ambient.
Press the down arrow key to display the second
screen:
11.5.4. Screen 2: Sensor Data
Register
• BOX T is enclosure temperature in degrees C
along with the raw voltage from the

temperature sensor.
• BOX V is box temperature sensor output

voltage.
• BNCH T is optical bench temperature in

degrees C. The current IR sensor temperature in
degrees C as well as the raw voltage coming
from the temperature sensor itself. This value
can range from ambient to a15 degrees
C.
• BNCH V is bench temperature sensor output
voltage.
Press the down arrow key to display the third screen:
11.5.5. Screen 3: Sensor Data
Register
• AMB P is measured every purge cycle with the
sample pump off and the manifold open. Its

value is weather and altitude dependent and can
range from 10.0 to 15.5 PSIA.
• BNCH Z is optical bench temperature in

degrees C at last zero interval.
• BOX Z is box temperature in degrees C at last
zeroing.
Press the down arrow key to display the fourth screen:
