Slow or No
Response/
Difficult or
Unable to
Calibrate
• Detector responds
slowly or does not
respond during
response test.
• Unable to accurately
set the zero or
response reading
during calibration.
• Detector 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 detector housing
cap is wet or clogged
with dirt or other
particulates.
• The calibration gas is
not an appropriate
concentration.
• The detector is
malfunctioning.
1. Verify that the calibration cylinder
contains an adequate supply of a
fresh test sample.
2. Check the detector housing cap to
determine if the flame arrestor is wet
or dirty. Clean if necessary.
3. 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.
4. If the calibration/response difficulties
continue, replace the plug-in sensor
as described later in this section.
5. If the calibration/response difficulties
continue, contact RKI for further
instruction.
