3. Verify that the Eagle is operating correctly. Use the RKI Bump Test Kit to
easily verify correct operation of the Eagle.
WARNING: If the Eagle does not respond to verification, take it to a known
“fresh-air” environment, then perform the demand zero
procedure described in “Preparing for Calibration” on page 46.
Repeat step 3 before using the Eagle in a potentially hazardous
location. If readings are not within 10% of the gas
concentrations, calibrate the Eagle as described in “Calibrating
the Eagle” on page 47.
Normal Operation
The Eagle continuously monitors the atmosphere around the Remote
Detector and displays the gas concentrations present for its target gases. In a
low-light environment, press any button to turn on the display backlight. (See
“Updating the Back Light Setting” on page 41 to program backlight
duration.) If the Confirmation Beep option is turned on, the Eagle beeps once
every 15 minutes to verify that it’s on the job.
To use an extender cable, see “Starting Up the Eagle” on page 11, insert the
Remote Detector into the monitoring area, then wait a few seconds for a
response.
Monitoring Combustible Gas in the PPM Range
1. Start the Eagle in the LEL range as described in “Starting Up the Eagle”
on page 11.
2. Allow the combustibles sensor to stabilize (3 to 5 minutes). This
stabilization period is required for the PPM range only.
3. Press the LEL/PPM button. The Eagle displays PPM in place of LEL%
for combustible gas, and the gas reading displays in parts per million.
4. If the PPM reading is not zero, take the Eagle to a fresh air environment,
then perform the demand zero procedure as described in “Preparing for
Calibration” on page 46.
NOTE: For the data logging option, combustible gas readings are logged in
%LEL regardless of the LEL/PPM setting.
