CALIBRATION PROCEDURES
This section describes the calibration procedures for the T100. All of the methods
described in this section can be initiated and controlled through the COM ports.
IMPORTANT
If you are using the T100 for US-EPA controlled monitoring, refer to Section 7 for
information on the EPA calibration protocol.
6.1. CALIBRATION PREPARATIONS
The calibration procedures in this section assume that the analog range and units of
measure, range mode, and reporting range have already been selected for the analyzer. If
this has not been done, please do so before continuing (refer to Section 4.6 for
instructions).
IMPORTANT
It is recommended that the LAMP CAL routine (refer to Section 4.8.7) be performed prior
to all calibration operations. This will allow the instrument to account for minor changes
due to aging of the UV lamp.
6.1.1. REQUIRED EQUIPMENT, SUPPLIES, AND EXPENDABLES
Calibration of the T100 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).

Traceability Standards
6.1.1.1. 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
2
measuring devices, zero
air should be similar in composition to the sample gas but devoid of SO
2
and large
amounts of hydrocarbons, nitrogen oxide (NO) and with a water vapor dew point
≤ -15°
