Statistics
The statistics menu allows you to view computed statistics for
each test (up to 100 tests) that have been made using Run
Manual, Run Prog 1 or Run Prog 2 data logging methods. The
statistics computed by the SidePak AM510 include:

Max: Maximum concentration value recorded (mg/m
3
)

Min: Minimum concentration value recorded (mg/m
3
)

Avg: Average of recorded concentration values
(mg/m
3
)

TWA: 8-hour time-weighted average (mg/m
3
)

Time: Elapsed time of test

Zero Cal
For best results, it's important to zero the AM510 prior to each
test. This ensures more accurate data, especially for low aerosol
concentrations. This process only takes a few minutes.

attach it to the inlet of the SidePak monitor.
2. If necessary, start the AM510 by pressing the PAGE key.
After the monitor goes into SURVEY MODE, press the PAGE
