The 4501-XX Toxic Gas Sensor Module utilizes a visual menu system operated by means of a magnet. A 
magnet stick is supplied for this purpose.  The menu system is used to calibrate the sensor module, and for 
maintenance and diagnostic procedures. 

The following adjustments can be made to the sensor module: 



  Range adjustments (see section 5.4) 



  4mA and 20mA calibration adjustments (see section 5.4) 



  Span adjustment (see section 6.3.1) 

The module menu system is operated by means of directing the magnet stick toward each of four independent 
hall-effect magnetic switches. Each switch functions as if it is a manually activated panel key.  The keys are 
located under the faceplate above and below the LCD and are labeled
