Ensure the surrounding environment is free from target and interfering gases. Navigate to the Calibration Menu using the magnetic wand. Select Zero Calibration .
The XNX display shows specific code types when the unit encounters operational problems. Code Category Typical Action
Connect 24 VDC to terminal M-1 (+), terminal M-2 (-), and the ground wire to the internal earth terminal M-3 . Xnx Universal Transmitter Quick Start Guide
Routine calibration ensures accuracy and system reliability. Always allow the sensor to stabilize for at least 30 minutes after power-up before performing a calibration. Required Equipment
Ensure the transmitter certification matches the hazardous area classification of your site (e.g., ATEX/IECEx or UL/cUL Class I, Div 1). Ensure the surrounding environment is free from target
Position the unit based on the target gas density. Place it low for heavy gases like Hydrogen Sulfide ( H2Scap H sub 2 cap S ) and high near the ceiling for light gases like Hydrogen ( H2cap H sub 2 ) or Methane ( CH4cap C cap H sub 4 Mounting Steps
The Xnx Universal Transmitter Quick Start Guide succeeds at its primary mission: getting the device installed and operational in under 15 minutes for a trained technician. It is well-structured, safety-conscious, and visually supportive. The XNX display shows specific code types when
Fixed-flow regulator (recommended flow rate: 0.5 Liters per minute). Non-absorbent calibration tubing. XNX Calibration cup adapter. Step 1: Zero Calibration
The sensor output has drifted significantly below zero. Re-zero the unit in clean air.
The XNX utilizes a non-intrusive magnetic user interface. Pass the magnetic wand over the glass window to navigate menus without opening the explosion-proof enclosure.
Zero calibration, span calibration, and functional bump tests.
