Model 360E Instruction Manual Getting Started
EXAMPLE: If the application is to measure between 0 ppm and 500 ppm, an appropriate Span Gas
would be 400 ppm. If the application is to measure between 0 ppm and 100 ppm, an appropriate Span
Gas would be 80 ppm.
Span Gas can be purchased in pressurized canisters or created using Dynamic Dilution Calibrator
such as the Teledyne Instruments Model 700 and a source of dried air scrubbed of CO
2
such as a
Teledyne Instruments Model 701 Zero Air Generator in combination with a canister of indicating
soda lime (such as Teledyne Instruments P/N 037600000).
Zero Air
is similar in chemical composition to the Earth’s atmosphere but scrubbed of all
components that might affect the analyzer’s readings.
In the case of CO
2
measurements this means less than 0.1 ppm of CO
2
and Water Vapor (when
dew point <-15˚C). Zero Air can be purchased in pressurized canisters or created using a Teledyne
Instruments Model 701 Zero Air Generator in combination with a canister of indicating soda lime
(such as Teledyne Instruments P/N 037600000).
3. Attach an exhaust line to the exhaust outlet port.
The exhaust from the pump and vent lines should be vented to atmospheric pressure using
maximum of 10 meters of ¼” PTEF tubing.
CAUTION
Venting should be outside the shelter or immediate area surrounding the instrument.
4. Attach a source of dried air scrubbed of CO
2
to the purge inlet port.
NOTE
The minimum gas pressure of the source of purge air should be 7.5 psig.
If the source of the purge air is shared by a Teledyne Instruments M700 (as shown in
figure 3-7) the minimum gas pressure should be 25 psig and should not exceed 35 psig.
5. Once the appropriate pneumatic connections have been made, check all pneumatic fittings for leaks
using a procedure similar to that defined in Section 9.3.3.
