CHAPTER ONE
Instructions for Operation
(for firmware version 1.32)
This chapter discusses the proper steps to safely operate the ODORATOR 2. Also included are
procedures for periodic testing and identification of the ODORATOR 2
’s controls.
WARNING:
DURING OPERATION, KEEP THE ODORATOR 2 AWAY FROM OPEN FLAMES. INLET SUPPLY
SHOULD NOT EXCEED 4 PSIG AND 1/4 PSIG (7 INCHES WATER COLUMN) IS RECOMMENDED.
**NOTE**
Connect the ODORATOR 2 to the gas supply with a non- absorbing, odor-free hose or
tubing such as high grade urethane, PVC or Tygon. Tygon tubing is recommended.
**NOTE**
Operators of the ODORATOR 2 should be selected with due consideration to
smoking habits, colds, and other conditions of health since these factors affect the sense of
smell. It is desirable to select o p e r a t o r s with an average sense of smell in order to
obtain reasonably consistent results from the use of the ODORATOR 2.
**NOTE**
See Figures 1 and 2 on pages 9 and 10 to reference the top panel layout and rear
case view for the following steps.
**NOTE**
All valves must be closed and the ODORATOR 2 turned
“OFF”.
Odor Threshold Level and Relative Odor Intensity Tests Procedure
1. Prior to attaching the sample hose, sniff the sample hose and verify no odor is detected. If
odor is detected replace the sample hose.
2. Connect the sample hose to the gas supply outlet valve and to the ODORATOR 2 inlet
port. Squeeze the inlet port lock to disengage while connecting or disconnecting.
3. Wake the ODORATOR 2 up by holding down the
“PWR” key until the display becomes
active. After booting up, the LCD will show the present live reading which will typically be
“0.00” with no gas flowing into the instrument. If the reading is not “0.00”, verify all valves
are closed and then
press the “ZERO” key to automatically zero the reading. If gas flow is
detected, “CLOSE” “VALVE” will be displayed for 5 seconds before returning to live
readings. Verify all valves are closed before repeating zeroing by again pressing the
“ZERO” key. While zeroing, the ZERO icon will flash. When complete, the new zero
reading along with the non-flashing ZERO and VIEW icons will be held in the display.
Press the
“ * ” key to return to live readings.
**NOTE** Should
the battery pack be changed,
or the LCD displays “RESET” “ZErREF”, perform
Zero Reset as stated on page 11.
