Frequently Asked Questions
7. 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 cc/min ±10%. See Section 9.3.4.
8. How long does the IR source last?
Typical lifetime is about 2-3 years.
9. Where is the sintered filter/sample flow control orifice?
These components are located inside the Flow Control Assembly that is
attached to the inlet side of the sample pump, see Figure 3-6. See Section
11.6.1 for instructions on disassembly and replacement.
10. How do I set up a SEQUENCE to run a nightly calibration check?
The setup of this option is located in Section 7.4.
11. How do I set the analog output signal range and offset?
Instructions for this can be found in Section 6.5.
12. What is the averaging time for an M300E?
The default averaging time, optimized for ambient pollution monitoring, is 150
seconds for stable concentrations and 10 seconds for rapidly changing
concentrations; see Section 10.5.1 for more information. However, it is
adjustable over a range of 0.5 second to 200 seconds (please contact
customer service for more information).
