12. If the exhaust does not have a readily detectable odor repeat step 11. If
the exhaust does have a readily detectable odor, push and hold the read
switch down and record the percent gas in air by volume reading as
shown on the LCD. This reading is the readily detectable level which
should be noticed by the average person’s sense of smell.
13. Close the gas supply outlet valve, the flow metering valve and then
disconnect the sample hose from the gas supply outlet.
14. Leave the ODORATOR “ON” for approximately one minute after the
test to purge the mixing chamber.
15. Turn the ODORATOR “OFF”.
16. If chosen, correct the reading value using the correction chart. The
correction chart is included to linearize the instrument in its range.
To use the chart, take the ODORATOR readily detectable level
reading and look up and record the corrected actual % gas value.
For ODORATOR readings not specified within the chart, linearly
interpolate between the next highest and lowest points on the chart. Do
not extrapolate beyond the readings in the chart. The readily detectable
level reading and, if chosen, the corrected actual value must meet
the requirements of the user’s company operations procedures.
Use at Elevation. See Appendix C, page 11.
