7. CALIBRATION PROCEDURES

This chapter describes the calibration procedures for the M100E. All of the methods
described in this section can be initiated and controlled through the COM ports.
If you are using the M100E for US-EPA controlled monitoring, see Chapter 8 for

7.1. Calibration Preparations

The calibration procedures in this section assume that the analog range and units of
measure, range mode, and range maximum concentration have already been selected for
the analyzer. If this has not been done, please do so before continuing (Section 6.5 for
instructions).

7.1.1. Required Equipment, Supplies, and Expendables

Calibration of the Model 100E analyzer requires a certain amount of equipment and
supplies. These include, but are not limited to, the following:
• Zero-air source
• Sulfur dioxide span gas source
• Gas lines - all gas line materials should be Teflon-type or glass.
• A recording device such as a strip-chart recorder and/or data logger
(optional).

7.1.2. Zero Air

Zero air is similar in chemical composition to the Earth's atmosphere but scrubbed of all
components that might affect the analyzer's readings. For SO
air should be similar in composition to the sample gas but devoid of SO
amounts of hydrocarbons, nitrogen oxide (NO) and with a water vapor dewpoint
≤ -15° C.
Devices such as the API Model 701 zero air generator that condition ambient air by
drying and removal of pollutants are available. We recommend this type of device for
generating zero air.

7.1.3. Gas Standards

Span gas is specifically mixed to match the chemical composition of the gas being
measured at about 90% of the desired full measurement range. For example, if the
