Steps
1. Install the equipment in a fixed position to ensure that the working environment meets the requirements.
Connect the power supply and output interface, such as RS485 or 4-20mA signal cable.
3. Use the infrared remote control for parameter setting, including alarm point modification, concentration calibrating, zero point calibrating, etc.
4. Start the device, warm up for 10 seconds, and start real-time monitoring.
5. View gas concentration data through LCD screen or remote monitoring system.
Notice
• Ensure that the Ambient Temperature is in the range of -30~ 50 ℃ to avoid condensation.
• Pay attention to explosion-proof requirements during installation and avoid use in non-designated dangerous places.
• Regularly calibrate and maintain to prevent long-term drift from affecting accuracy.
• When operating with an infrared remote control, avoid opening the lid in a non-safe environment.
• Power supply voltage must be kept within the range of DC5V +/- 1% or DC24 +/- 1%.
