Slow or No
Response/
Difficult or
Unable to
Calibrate
•
Beacon 200
responds slowly or
does not respond to
response test.
•
Unable to
successfully set the
fresh air or span
reading during
calibration.
•
Beacon 200
requires frequent
calibration.
Note:
Under “normal”
circumstances, the
detector requires
calibration once every 3
months.
Some applications
may require a more
frequent calibration
schedule.
•
The calibration
cylinder is low, out-
dated, or defective.
•
The flame arrestor in
the H
2
S detector
housing cap is wet or
clogged with dirt or
other particulates.
•
The detector is
malfunctioning.
•
The main PCB is
malfunctioning.
1. Verify that the calibration cylinder
contains an adequate supply of a
fresh test sample.
2. Verify that the calibration gas
concentration is appropriate for the
detector. Zero emission air (0 ppm
H
2
S) is normally used for a zero
adjustment if the environment is
suspect and 25 ppm H
2
S in nitrogen
is normally used for a response
adjustment.
3. Check the H
2
S detector housing cap
to determine if the flame arrestor is
wet or dirty. Clean if necessary.
4. If the calibration/response difficulties
continue, replace the detector.
5. If the calibration/response difficulties
continue, contact RKI for further
instruction.
