1. Calibration of “Zero Position”After preheating the sensor for 20 minutes, connect the sensor gas chamber to the air sample bag using a rubber hose → Use the remote control to set the sensor to the “zero display interface” → Open the calibration gas sample bag, adjust the flow meter to the flow and ventilation time values specified by the sensor calibration → Use the remote control to set it to “zero position” → Close the calibration gas sample bag and the adjusting valve → Use the remote control to cycle the sensor back to the “normal display interface” for storage.2. Calibration AccuracyConnect the sensor gas chamber to the methane calibration gas sample bag using a rubber hose → Open the gas sample bag → Adjust the flow meter to the flow and ventilation time values specified by the sensor calibration → Use the remote control to adjust the displayed value to match the standard gas sample value → After the displayed value stabilizes for 90 seconds, close the methane calibration gas sample bag and flow meter → When the displayed value drops below the safe concentration, use the remote control to cycle the sensor back to the “normal display interface” for storage.3. Setting Alarm PointsUnlock the remote control → Press the function key to enter the alarm point setting mode → Adjust to the desired alarm point value → Press the “confirm key” to save the alarm value and return → Exit the setting state.4. Testing Sound and Light AlarmUnlock the remote control → Press the function key to enter the alarm point test mode → Press the “confirm key” → Activate the sensor to emit sound and light alarms → Press the “cancel key” to exit the sound and light alarm test state.
