The command variable is used to stop WCT, start WCT, and do auto-calibration. 

•

 

QFactor

 

This block contains the variables for Q factor detection. 

•

 

Test

 

This block contains some variables for debugging. 

•

 

Protection

 

This block contains protection variables, such as input voltage protection, input current protection, and 
temperature protection. 

•

 

KeyFOB

 

This block contains the variables used for KeyFob. 

NOTE 

Besides the variables above, all the global variables can be added to 
FreeMASTER. The procedure to generate and add variables to watch 
window is described in the FreeMASTER user manual. 

 

5.3  Application parameters modification 

The application parameters (NVM parameters) can be easily viewed and changed on the control panel. 
The control panel contains the web page elements (buttons, check boxes, and text fields) that enable a 
user-friendly way to visualize and change the application control parameters.
