3.3 Dilution Fitting
The user may wish to install a dilution fitting in front of the
RAE-SEP tube to dilute the gas samples. One application for a
dilution fitting is to measure organic gas when the concentration
exceeds the upper limit of the sensor range.
Make sure to set the dilution ratio in the programming mode
(see Section 4.3) so that the correct gas reading will be
displayed when the dilution fitting is used.
WARNING: To use a dilution fitting, the user
must have the monitor located in a clean
atmosphere outside the confined space and use a
remote access probe or inert tubing to measure
the gas concentration inside the confined space.
