Response Test
A response test is recommended before each use. Table 19 lists methods for
generating gas that are appropriate for a target gas. Contact ATI for details on other
methods.

Some of the methods above produce high gas levels in closed containers. It is best to
approach the opening of the container, slowly, with only the tip of the wand, to reduce the
level of exposure at the sensor. While a high exposure will not harm the sensor, it may
take several minutes for it to recover.
Do not draw liquid into the wand. Sample the air space just above the liquid.
