Before sealing the cord grip, ensure the instrument is running properly:
a. With power cable, ASC, and ambient temperature sensor cables properly
connected power up the instrument and wait until the LED temperature
stabilizes (~10 minutes).
b. Perform Ambient Temperature Sensor verification (Section 4.1) first.
c. Following temperature sensor verification, perform Pressure verification
(and calibration if necessary) (Section 4.2).
d. Following pressure sensor verification, perform Sample Flow verification
(and calibration if necessary) (Section 4.3).
e. Next, for the 640x option, perform the Bypass Flow verification (and
calibration if necessary) (Section 4.4); if no option, skip to next step.
f.
Next, perform PMT verification with SpanDust™ and adjust as necessary
(Section 4.5).
g. Last, perform the Leak Check (Section 4.6)

Once the T640 instrument is determined to be installed and working properly,
tighten up the roof flange cord grip around the sample line.
17.
Apply
clear silicone caulk
generously around the top end of where the cord
grip rubber grommet meets the sample line to ensure complete sealing from
the weather.
•
Silicone caulk seals well and can easily be removed and reapplied if the
instrument needs to be removed for servicing.
18.
Additionally, tighten up the tripod cord grip and lock down the feet of the
tripod to fully secure the sample line.
OUTDOOR ENCLOSURE INSTALLATION
1.
Place enclosure in the location where the instrument is to run.
2.
The T640 instrument should be installed in the enclosure at a height where
the inlet will be 2 m above ground (the base of the enclosure).
•
Make sure the optical sensor nozzle and nozzle to ASC adapter are
installed on the optical sensor.
3.
Once the T640 is in the enclosure and lined up with the cord grip opening on
the top of the enclosure, insert the ASC into the cord grip (from above) and
slide it down gently until it inserts into the ASC support of the T640.
•
The ASC should go into the T640 level and plumb, and is in completely
when it is felt to bottom out onto the top of the optical sensor. This can
be checked by lowering the front panel of the T640 and making sure the
base of the ASC is touching the top of the optical sensor flush.
