Box
Temperature
ñ
This
is
the
current
internal
enclosure
temperature
along
with
the
raw
voltage
from
the
temperature
sensor,
and
has
the
same
range
as
line
8.
LINE
11:
Pressure
ñ
This
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
(line
12).
LINE
12:
Vacuum
ñ
The
vacuum
pressure
is
measured
every
purge
cycle
by
closing
all
sample
valves.
Itsí
value
is
typically
2.5
to
4.0
PSIA
below
ambient
(line
12).
LINE
13:
Ambient
ñ
Ambient
pressure
is
measured
every
purge
cycle
with
the
sample
pump
off
and
the
manifold
open.
Itsí
value
is
weather
and
altitude
dependent
and
can
range
from
10.0
to
15.5
PSIA.
