Standards
GB/T3836.1-2021、GB/T3836.31-2021、GB3836.15-2000、GB12476.1-2013、GB12358-2006、GBZ2.1-2007、GB4208-2008
Steps
1. Install the tester to ensure that the electrical interfaces and cables are connected correctly.
Connect the Power Supply (DC24V).
3. Use the remote control to set the alarm value, zero, calibrate, reset or modify the address code.
4. Monitor gas concentration data on the LCDTFT display.
5. Connect Output signal to Control system or alarm device as needed.
Notice
• Operating ambient temperature range is -20~ 50 ℃, Humidity is 10-95% RH (no condensation).
• Sensor life is 2 to 3 years, depending on the Operating Environment.
• When connecting the cable, choose three-core Shielding cable for 4~ 20mA, four-core for RS485, and when the distance exceeds 1000 meters, the single wire diameter is ≥ 1.5mm. Shielding layer needs to be grounded.
• The explosion-proof form is explosion-proof to ensure safe use in dangerous places.
Alarm settings support regular high and low alarms and interval control alarms.
• Optional Accessories such as Power Adapters and monitoring accessories need to be configured according to requirements.
