Sharing is the greatest support, and following is the best encouragement
1. Calibration of the “Zero Point” After preheating the sensor for 20 minutes, connect the sensor’s 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 calibrated flow and ventilation time values of the sensor → Use the remote control to set it to “zero point” → Close the calibration gas sample bag and the adjustment valve → Use the remote control to cycle the sensor back to the “normal display interface” for storage.2. Calibration Accuracy Connect the sensor’s gas chamber to the methane calibration gas sample bag using a rubber hose → Open the gas sample bag → Adjust the flow meter to the calibrated flow and ventilation time values of the sensor → 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 → Wait for the displayed value to drop below the safe concentration, then use the remote control to cycle the sensor back to the “normal display interface” for storage.3. Setting Alarm Points Unlock 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 Alarms Unlock 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.
