1. Installation and fixation: Choose Wall-Mounted or pipeline installation according to the site conditions. Connect the power supply and signal line: Connect a 12-30VDC DC power supply (standard 24V), and connect the corresponding cable according to the output signal type (e.g. 4-20mA or RS485). 3. Boot and initialization: Power on, the instrument starts and performs self-test. 4. Parameter settings: Use the standard infrared remote control or through the Miscellaneous compatible system to set parameters such as alarm points, units, and display modes. 5. Calibrating operation: In a safe environment, use the infrared remote control for zero-point calibrating or concentration calibrating. The instrument has the function of misoperation identification. 6. Operation monitoring: The instrument starts continuous online monitoring, and the real-time concentration is displayed on the 1.7-inch color screen. 7. Alarm processing: When the concentration exceeds the standard, the instrument will trigger the set alarm mode (such as relay output, sound and light alarm, etc.). 8. Data viewing and maintenance: Data, alarm records and instrument logs can be viewed through the display screen or remote monitoring center, and regular maintenance or Sensor replacement can be performed according to the log reminder.
● When installing, ensure that the sampling method (diffusion, pipeline, flow or pump suction) is suitable for the on-site environment. When connecting the cable, it is recommended to use a three-core Shielding cable for 4 to 20mA output, and a four-core cable for RS485 output; when the transmission distance exceeds 1000 meters, the single wire diameter should be ≥ 1.5mm, and the Shielding layer needs to be grounded. The power supply needs to use a DC regulated switching power supply, and the standard power supply for a single device is 24V, 1A or greater than 1A. The instrument is explosion-proof, but the installation and operation still need to comply with the safety regulations of the relevant dangerous places. When calibrating, ensure that it is operated in a safe and calibrated environment to avoid misoperation. ● Optional functions (such as wireless transmission, high temperature detection, sound and light alarm, etc.) should be clear when booking. ● Instrument working environment humidity range is ≤ 10~ 95% RH, built-in Filter can be used in high humidity or high dust environment, but still need to pay attention to the impact of environmental conditions on long-term stability. ● Sensor life is about 2 to 3 years, need to pay attention to the instrument log life expiration reminder and timely replacement. ● Ensure that the Instrument Protection Rating (IP65) meets the installation environment requirements.
