INTRODUCTION
You have purchased the highly sensitive
FORENSICS DETECTORS
extremely low levels of carbon monoxide (CO) in compressed
gas or ambient air. It can be used test gas quality in scuba
cylinders or to monitor exposure to CO in the ambient air.
For critical applications, calibrate every 6 months and bump
test daily, or before use, to verify detector operation.
OPERATION
Press the POWER button to turn the unit on. The preset
alarm levels will be shown followed by a 60-second
countdown. Once complete, the unit will beep and be ready
to analyze CO content in air or other gases. The current CO
concentration will be displayed. CO concentrations
exceeding the preset alarm points will trigger an
audio/visual/haptic alarm. To turn the unit OFF, hold the
POWER button for 3 seconds.
SCUBA CYLINDER TESTING
To test the contents in a scuba cylinder, securely fasten the
calibration cap clip to the unit. Ensure the clip is aligned over
the white sensor hole, then place the rubber dome on the
barb. Gently open the cylinder valve to allow a small amount
of gas to flow (a light hissing sound). Place the dome over
the cylinder valve outlet and allow gas to flow for about 15
seconds. Ideally, the CO concentration in your breathing gas
should be 0 ppm. Divers Alert Network (DAN) recommends
less than 5 ppm for safe diving. The Compressed Gas
Association (CGA) limit is 10 ppm.
AMBIENT AIR TESTING
To monitor ambient air, remove the rubber dome and
calibration cap clip if fitted. Ensure the white sensor hole is
unobstructed. Place the detector in the area to be
monitored. The unit may remain on for as long as needed.
