1  INTRODUCTION 

Important information: Read the manual carefully before using the device.  

Inappropriate utilization may cause damage to the device, to the DUT (device under test), and/or other 

components of your setup.  

Keep these instructions in a safe place and pass them on to any future user.  

1.1  Conformity 

We, Image Engineering GmbH & Co. KG, hereby declare that the LG4 corresponds to the essential 

requirements of the following EC directive:  

 

Electromagnetic Compatibility - 2014/30/EU 

 

Photobiological safety of lamps and lamp systems - IEC 62471:2009 

1.2  Intended use 

The LG4 is a high intensity illuminator for transparent charts based on LED technology. The device 

can be controlled over the integrated rotary knob and over the LG Software.  

 

Only suitable for indoor use. 

 

Place your system in a dry and constant tempered environment without any interfering 

light. 

 

The optimal ambient temperature range is 22 to 26 degrees Celsius. The maximum 

ambient temperature range is 18 to 28 degrees Celsius. 

 

The system has an internal temperature management system, if there is any error 

regarding the internal temperature the system automatically turns off to avoid any 

damage

.

 

 

1.3  General safety information 

Do not

 open the device without any instructions from the Image Engineering support team or when 

connected to the power supply. 

1.3.1  Eye safety 

The LEDs used in the LG4 can be classified as belonging to the Exempt Group or Risk Group 1 

according to IEC 62471:2009.
