Model 6200E Instruction Manual Calibration Procedures
M6200E Rev: A1 157
7. CALIBRATION PROCEDURES
This chapter describes the calibration procedures for the M6200E. All of the methods described in
this section can be initiated and controlled through the COM ports.
NOTE
If you are using the M6200E for US-EPA controlled monitoring of SO
2
, see Chapter 8 for
information on the EPA calibration protocol.
7.1. Calibration Preparations
The calibration procedures in this section assume that the analog output reporting range and units
of measure, reporting range mode, and reporting range span have already been selected for the
analyzer. If this has not been done, please do so before continuing (Section 6.7 for instructions).
Also, unless otherwise stated, the procedures in this Chapter are written with the assumption that
the M6200E is being used in its default configuration as an H
2
S analyzer. The same methods and
setups can be followed when the instrument is configured for SO
2
measurement by substituting
SO
2
span gas for the H
2
S span gas listed in the procedure.
For analyzers configured in H
2
S Æ SO
2
multigas mode, see Section 7.8
NOTE
In applications where the instrument may be used to measure SO
2
as well as H
2
S make
sure that the calibration gas being used matches the gas measurement mode in which
the instrument is set during the calibration procedure.
7.1.1. Required Equipment, Supplies, and Expendables
Calibration of the Model 6200E analyzer requires a certain amount of equipment and supplies.
These include, but are not limited to, the following:
• Zero-air source
• Hydrogen sulfide 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).
