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
2. Connect DC24V Power Supply
3. Set the alarm value, zero adjustment, calibrating and other parameters through the remote control or Operating interface
4. Monitor the gas concentration data displayed on the LCDTFT display
5. Control system according to Output signal
Notice
• Operating voltage range is DC12V~ 30V to ensure stable power supply
• Ambient Temperature -20~ 50 ℃, Humidity 10-95% RH (non-condensing)
• When the cable transmission distance exceeds 1000 meters, the single wire diameter is ≥ 1.5mm, and the Shielding layer needs to be grounded
• Sensor life is about 10 years, the actual life depends on the Operating Environment
• The explosion-proof form is explosion-proof, and the installation must meet the explosion-proof requirements
• Optional Measurement Certificate, user pays
