8.3 ZERO/SPAN CHECKING

It is recommended that the Model 300 be checked daily for zero and span drift.

The EPA requires that the Analyzer be zero and span checked at least once every two weeks.

With the Automatic Zero/Span Check and Remote Zero/Span Check features of the Model 300, daily zero and span checks are easy.

For Automatic Zero/Span Check and Remote Zero/Span Check to be effective, it is necessary that the Analyzer have the Zero/Span valve option. This option includes the two three-way stainless steel valves and requires user-supplied sources of zero air and span gas.

Operating instructions for Automatic Zero/Span Check and Remote Zero/Span Check are described in Sections 3.4 through 3.7.
