You perform a quick "bump test" by applying a known concentration of gas. The transmitter displays the reading, confirming the pre-calibrated sensor is communicating correctly with the main board without needing a full span calibration. Key Quick-Start Specifications Power Supply 16 to 32 VDC (sensor dependent) Communication 4-20mA with HART (standard); Modbus or Fieldbus (optional) Display Backlit LCD with text, bar graphs, and status icons Mounting Surface lugs, pipe mount (2–6"), or ceiling bracket Operating Temp -40°C to +65°C (-40°F to +150°F) Important Maintenance Tips

Imagine you are a technician tasked with setting up a new gas detection point in a chemical processing plant. To ensure a safe and efficient setup, you follow these essential steps from the XNX Quick Start Guide :

The XNX utilizes a non-intrusive magnetic interface. Use the magnetic wand provided with the unit to trigger the four software keys on the glass window:

Once wired and powered up, the XNX initializes a self-test sequence. Non-intrusive configuration is performed using the magnetic wand against the glass interface window, avoiding the need to open the enclosure in hazardous environments. 1. Navigation Basics
