1. Install a fully charged battery pack by aligning
the top of the battery with the latches in the

powers up, then release the power button.
Charger cord must be unplugged from IRED.
4. Allow unit to go through the warm up sequence
in clean air. At the end of warm up, the unit will
perform a “cell check” and enter the working
display. This requires 20 to 25 minutes.
5. Look at the display – Ready for Measurement
and function indicators will be displayed.
6. Bump test the IRED with recommended
10ppm ethane/1000ppm methane
to verify accuracy. (optional)
7. Attach any probe to the lter
assembly (survey or barhole probe).
8. Place your nger over the inlet and wait ~5
seconds for “FLOW BLOCKED” to appear
on the display. If the instrument does not
show “FLOW BLOCKED,” service is required.

QUICK-START INSTRUCTIONS
9. You are now ready to use the instrument.
“For Best Results: Using a gas detection
device capable of sensing low level
natural gas concentrations, conrm
a gas measurement in a range of 50
- 2000ppm prior to use of the IRed”
10. Press the “B” button and follow the directions
on the display to perform a measurement.
The IRED will sample for 40 seconds and
update the display readings at 10 second
intervals. If sample concentration is too
large, the display will read “background
too high.” Back off the probe to dilute
the sample. It may be necessary to retest.
11. The “C” button allows you to view the
menu functions, turn the pump on or off,
and print the result after a measurement.
12. Measurements will automatically be stored
to the instrument’s memory with GPS
coordinates (GPS is an optional feature).
Measurements can be viewed on the
display of instrument or through Smartlink.
13. To Power Off or enter Stand By, press and
hold the “A” button for 5 seconds until the
