XNX Universal Transmitter - Merkantile

XNX Universal Transmitter3.1 Gas Calibration MenuEach of the sensor technologies supported by the XNX UniversalTransmitter uses unique calibration procedures. The descriptionprovided illustrates the XNX interface to the sensor device and doesnot replace the procedures found in each device operating manual.For the XNX EC sensors, the calibration procedure is covered inSection 3.2.2.The Gas Calibration menu is used for Zero and Span calibration aswell as functional gas testing (bump test). The Gas Calibration menuis accessed from the main menu screen.Figure 3-1.

Correctoperation of each sensor/detector should be confirmed withtest gas of known concentration before each use.See Section 6 - Specifications for Calibration Gas specifications.3.2.1 Calibration ProcedureThe following section outlines the steps for calibrating the XNX attachedsensors. Calibration information for specifc sensors follows.Note:Follow the specific procedure outlined in the Operating Manualfor each sensing device.1. If using compressed gas cylinder, push the calibration gas flowhousing onto the bottom of the sensor and apply the gas.2. Access the calibration mode.Figure 3-2. Gas Calibration MenuNOTE:The Gas Calibration menu is for both Zero and Span Calibration.Section 3 - Calibration 3-2
