THE S-LINK DOUBLE CHANNEL LASER POWER/ENERGY METER 

 

 

 

1.1  Introduction 

To obtain full performance from the S-Link and the PC S-Link, we recommend that you read this manual 
carefully. 

The PC S-Link software transforms your PC screen into a large S-Link screen enabling you to control and 
see your information from a distance and transfer data to a PC for sophisticated data analysis. 

The S-Link is a microprocessor-based power and energy meter that uses the latest technology to provide 
a multitude of options in a user-friendly environment.  It is a complete power and energy meter that can 
provide a statistical analysis of your measurements. 

There is no need to enter the head specifications when connecting the new Gentec-EO power or energy 
detector  heads,  for  head  version  5  and  above.    The  S-Link  is  already  internally  set up  to  accept  all  the 
Gentec-EO Hi power  wattmeter and joulemeter heads with a  DB-15 connector  of head  version 5  and  6.  
The S-Link accepts the QE-xx-x-MT or a XLE-4.
