NO
2
, and SO
2
to various pollution units using CFR40 Part 60 emission
factors. Note that the pollution-unit conversions for NO, NO
2
and NOx are
based on the molecular weight of NO
2
.
Select to display pollution units in parts per million (ppm), pounds of pol-
lutant per million BTU (#/Mbtu), milligrams of pollutant per cubic meter
of gas (mg/m
3
), or grams of pollutant per gigajoule (g/GJ) as follows:
1. Display the MAIN MENU by pressing the
MENU (F2) button. If necessary, press ESC
until MENU appears above F2.
2. Use the buttons to highlight SETUP, and
