1  INTRODUCTION 

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

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

components of your setup.  

Please 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 

“LE7” corresponds to the essential 

requirements of the following EC directive:  

 

Electromagnetic Compatibility - 2014/30/EU 

 

RoHS 2 - 2011/65/EU 

 

Low Voltage - 2014/35/EU 

1.2  Intended use 

The LE7 is based on a 0,5 m integrating sphere and iQ-LED technology to illuminate transparent test charts. The 

LE7 is controlled with the iQ-LED control software or via dip switches directly on the device (without a connected 

PC). A micro-spectrometer is also included with the device. 

 

Only suitable for indoor use. 

 

Place your system in a dry, constantly tempered environment without light interference. 

 

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

temperature range is 18 to 28 degrees Celsius.  

 

The optimal system temperature range, displayed in the software user interface, is between 35 

and 50 degrees Celsius. The system has internal temperature management, if there is an error 

regarding the internal temperature, you will get a warning message, and the system will 

automatically turn off to avoid any damage.

 

 

1.2.1  Departing from described setup 

The following steps must be performed in the correct chronological order to allow smooth commissioning.  

 Departing from the chronology may lead to an incorrect working device.  

1.  Install the iQ-LED software 

2.  Connect LE7 to power and via USB to the PC  

3.  Switch LE7 on; the system drivers will be installed 

4.  Once the drivers are installed completely, you can start the software
