9
nose approximately 3/4 inch (20 mm) above the exhaust port and sniff the exhaust.
14. If the exhaust does not have a readily detectable level of odor, repeat step 13. If the exhaust
has a readily detectable odor, press the
“READ” key to record
the corrected RDL reading
level along with GNSS location and timestamp. The display may briefly show the
RDL icon and the test reading. The
Readily Detectable Level
should be detectable by
the average
person’s sense of smell.
15. If optionally enabled via OdorSeer Configuration, the instrument can now be used to
perform a
Relative Odor Intensity
(ROI) test. The LCD will
display “ROI x.xx” where “ROI”
will flash and “x.xx” is the live reading. Adjust the Flow Metering Valve to obtain the pre-
determined target reading on the LCD. If configured via OdorSeer, the pre-determined
target reading may be viewed by pressing and holding the “VIEW” key. Upon release, the
display will return to “ROI x.xx”.
16. Wait about 30 seconds, position the nose approximately 3/4 inch (20 mm) above the
exhaust port and sniff the exhaust. Rate the relative odor intensity on a scale from 1
– 5
where the relative odor intensity is:
1
– absent,
2
– barely detectable,
3
– readily detectable,
4
– strong or
5
– very strong or obnoxious.
17. Enter the rated odor relative intensity in the instrument by using the
“↑” or “↓” keys to
increment or decrement the count until the desired value is shown on the display. The
display count will change by one for each
“↑” or “↓” key press and alternate between “ROI”
and the count value. For example, after 5
“↑” key presses “5 0.80” would indicate a rating
of 5 relative to a test reading of 0.80 % gas in air.
18. P
ress the “READ” key to record the ROI rating along with ROI target value, actual
corrected % gas concentration, GNSS location and timestamp.
**NOTE**
The rating must be entered before the “READ” key will be active.
19. The display will show the RDL icon and test reading for 5 seconds. Should the RDL
reading exceed the configurable (via OdorSeer) RDL High Alarm, the display will show
“RDL” “HIGH” for 5 seconds along with an audible beep from the instrument to alert the
operator of the RDL test result. The ODORATOR 2 will now go into PURGE mode and the
display will show the PURGE icon, a flashing “ * “ and the live reading. The Flow Metering
Valve must be closed while in PURGE mode
and the live reading should be “0.00”. In
PURGE mode, the last set of readings may be reviewed by pressing
either the “↑” or “↓”
keys to scroll through the last ZERO, TDL, RDL and optionally ROI values. After the
PURGE mode times out the ODORATOR 2 will automatically power off and enter SLEEP
mode
(“ZZZZZ” will briefly display). During PURGE mode the LCD shows a flashing
asterisk
“ * ” to allow the operator to abort PURGE mode and re-enter CONDITIONING
mode for additional tests
by pressing the “ * “ key. The operator may also choose to press
and hold the “PWR” key to turn the ODORATOR 2 “OFF” after sufficiently purging the flow
system by entering SLEEP mode
(“ZZZZZ” will briefly display).
