Measuring and Viewing
Once you have setup your logging parameters and calibrated the instrument, you are ready to begin
measuring. The focus of this chapter is to give you a brief overview of what is measured, how to
navigate, what measurements screens will appear, and how to run and stop your measurements. The
chapter concludes with an explanation of the file system management functionality which is comprised
of the following: reviewing past measurements, deleting files, viewing file storage and memory, and
viewing the estimated run-time.
NOTE: The subsequent sections show examples of views which you may have disabled on your
instrument (refer to Chapter 3, “Setting-up the EVM” for more details).

take measurements.
With a couple pushes on the keypad buttons, you will be running and viewing your sessions. Following
your sessions you can load the data/files into DMS to manipulate, analyze, save, and create reports
(See Chapter 6 for viewing your logged data in DMS).
Quick Help List: typical gas/particulate/air quality overview
