: Perform regular bump tests to verify that the sensors are responsive, as outlined in the quick start video .
Set the full-scale range (typically 100) and the alarm thresholds (commonly Low Alarm at 20% LEL, High Alarm at 50% LEL). 4. Calibration Protocol for Flammable Gases
Connect a nominal 24V DC (16–32V DC range) power source. Catalytic bead sensors draw significant current because the active bead must be heated to induce surface oxidation of the target gas. Ensure the power supply can handle the peak startup inrush current.
