HAPSITE ER Operating Manual
NOTE: Calibration Mixes may be purchased from a variety of laboratory supply
businesses in liquid form, usually in a methanol matrix. Typical laboratory
mixes are readily available as off-the-shelf items, while custom mixtures
can be made to specifications.
13.1.5 Connecting the HSS to the HAPSITE
Determine a suitable location, on a level surface, where the HAPSITE and the HSS
are close enough together to connect via the Transfer Line. Refer to
section 2.5.2,
Installing the Headspace Sampling System, on page 2-13 for detailed installation
instructions.
CAUTION
Care must be taken to avoid sharp bends of the Transfer
Line, which could lead to flow restriction or breakage.
13.1.6 Providing Power to the HSS
The HSS may use AC power from an outlet, or may also use an INFICON
rechargeable battery. A description of the connections for each power supply
follows.
13.1.6.1 If AC Power is Available
If AC power is available, use the Y-cable furnished to "split" the 24 V(dc) power
from the HAPSITE’s AC to DC power converter. Connect one connector of the
Y-cable to the HAPSITE’s power connection and connect the other connector to the
back of the HSS. Then connect the two-cable connector to the output line of the AC
to DC power converter. Finally, plug the AC to DC power converter into the AC
power outlet.
Refer also to section 2.5.2, Installing the Headspace Sampling System, on page
2-13 .
NOTE: Do not use the Y-cable to power two HAPSITE instruments.
HINT: If the HAPSITE is not shut down, do not disconnect the power cable unless
a charged battery is installed.
13.1.6.2 If AC Power is Not Available
For field operations, or whenever AC power is not available, batteries must be
used. A battery will provide power to the HSS for approximately 3 hours of use,
depending on ambient temperature and the parameters of the method being used.
