Calibrate the Detector via the menu
1. Turn On the BW Flex Series detector, and wait to sensors warm up.
2. Double-press the button to enter the menu.
3. Single press the button to locate Calibration and hold the button to select it. The detector
starts Zero Calibration automatically.
4. After Zero Calibration is complete, place the cap over the detector, and press it down on both
tabs to snap it into place.
5. Attach the hose.
6. Follow on-screen instructions.
Note: If sensors fail to detect the gas, or cannot be spanned, repeat the calibration. If the
problem persists, replace the sensor.
7. Remove the calibration cap; the detector starts purging, and the slots LEDs flash amber
clockwise. After the purge is complete, the detector is back to the regular mode.
