Description:
This manual provides description and operating instructions for a redesigned Beta Gauge for measuring particles from vehicle exhaust. The improvements and a new control system including a control unit which is radically different from the prior unit, are described. Complete Beta Gauge operating instructions for Federal Test Cycles are included as well as set up and calibration procedures. A trouble shooting guide completes the manual with instructions for locating problems. The overall improvements provide (1) all necessary and computation of algorithms for automatic sampling and (2) processing of the variables to compute the final particulate emission rate in grams per kilometer. The instrument also has a single mode operation for sampling from sources with various concentration levels.
