Function

 

Description

 

  

 Firmware version 

  

 

This provides the controller firmware version release, serial number and 
controller type. 
   

 

 

  
Initiates a normalisation of the sensor array wire levels. 
 

 

 

 

 
 

 

Displays the x and y sensor wire array matrix levels.   Applying a touch to 
the sensor will register a response in the x and y wires levels.  This graph 
can be used to determine the correct operation of all the wires within the 
sensor.  This can be done by applying a touch to the sensor and moving 
your finger left to right then top to bottom over the sensor.   All wires 
should register a peak relative to your finger movement across the sensor.  

Please note:

touch operation is disabled when the Test Sensor page is open.  

The Test Sensor page can be terminated by using the Escape key via a 
connected keyboard or a mouse to press the Close button located in the 
bottom right hand corner of the page. 
 

  

 Threshold 

 

 

This allows the sensitivity of the sensor to an applied touch to be increased 
or decreased.   Lower values provide greater sensitivity and higher values 
provide reduced sensitivity.  Default value is 22. 
 

 

 

  
Initiates a controller firmware reset
