QUESTION ANSWER
How do I perform a leak check? Section 11.3.2 provides leak check instructions.
How do I measure the sample
flow? Sample flow is measured by attaching a calibrated rotameter, wet test
meter, or other flow-measuring device to the sample inlet port when the
instrument is operating. The sample flow should be 800 cm
3 /min 10%.
See Section 11.3.3.
How long does the IR source last? Typical lifetime is about 2-3 years.
Can I automate the calibration of
my analyzer? Any analyzer with zero/span valve or IZS option can be automatically
calibrated using the instrument’s AutoCal feature. The setup of this
option is located in Section 9.4.
Can I use the IZS option to
calibrate the analyzer? Yes. However, whereas this may be acceptable for basic calibration
checks, the IZS option is not permitted as a calibration source in
applications following US EPA protocols.
To achieve highest accuracy, it is recommended to use cylinders of
calibrated span gases in combination with a zero air source.
Q: What is the averaging time for
an GFC7001T/GFC7001TM? A: The default averaging time, optimized for ambient pollution
monitoring, is 150 seconds for stable concentrations and 10 seconds for
rapidly changing concentrations (see Section 13.5.1 for more
information).
However, it is adjustable over a range of 0.5 second to 200 seconds
(please contact Customer Service for more information).
