7. Place the cap over the detector, and then press down on both tabs to snap it into place.
8. Attach the hose.
9. Apply span gas when the sensor slot LEDs start flashing. The bump test starts after the BW
Flex Series detects gas. The four sensor slots LEDs flash blue clockwise. After the bump test
is completed, the LEDs are solid green if calibration passed, or red if failed.
Note: If sensors fail to detect the gas, or cannot be spanned, repeat the bump test. If the
problem persists, replace the sensor.
10. Remove the calibration cap. The detector starts purging, and the slots LEDs flash in amber
clockwise. After the purge is complete, the Detector is back to the regular mode.
