CAUTION
Move to a normal atmosphere (20.9% v/v O
2
) that is free of hazardous gas. Use 50% LEL for
test gas.
Details for calibration and maintenance:
l Recommendations for calibration of the equipment on a routine basis including the
maximum time interval between calibrations.
l Calibrate the apparatus before first-time use and then on a regular schedule, depending on
use and sensor exposure to poisons and contaminants. Honeywell recommends that the
sensors be calibrated regularly and at least once every 180 days (6 months).
l The combustible sensor is factory calibrated to 50% LEL methane. If monitoring a different
combustible gas in the % LEL range, calibrate the sensor using the appropriate gas.
Procedure to calibrate the detector via the calibration cap and the DC app on a
mobile device
1. Turn On the BW Icon. Place the cap over the detector, and then press down on both tabs to
snap it into place. Wait a few minutes to sensors warm up.
