1. Introduc on:

Thank you for choosing the ILT2500. The ILT2500 internal Datalight so ware was designed to be 
simplis c enough for easy touch screen opera on and advanced enough to meet the needs of 
researchers and scien sts. The ILT2500 works with hundreds of sensor/filter/op c combina ons and 
can be run using internal or PC so ware making it extremely versa le.

The ILT2500 System includes:

A. ILT2500 Meter – 

Auto ranging meter

.

B. USB Cable -  

 Micro and Mini USB cables for charging, so ware control and data retrieval.  

C. CC200 Case– 

Protec ve carrying/shipping case.

D. Electrical Calibra on Cer ficate

 – N.I.S.T. Traceable/ISO17025 accredited

.

E.  Datalight III PC/Mac computer so8ware-Free download on ILT website:

h3ps://www.intl-ligh3ech.com/support/so ware

All systems should be run using FW 3.1.4.7 or higher.

F. Sensor /detector (separate purchase required/sold separately).

Note: Instruc ons manuals and Datalight III so ware downloads are located on the ILT website:

3. Quick Reference Guide:
3A. Front:

 The front panel of the ILT2500 is a full color 4.3"

capaci ve TFT touch screen display. The display is a sensi ve
electronic device. It should not be exposed to sharp objects,
harsh environments, chemicals, liquids etc. 

3B. Rear:

  On the back of the ILT2500 is a stand which is

opened by grasping at the two finger slots and gently li ing
the stand up.  The stand has small posts that slide along the
housing to open and close.  No force should be applied to
the stand during opening and closing. When the stand is in use, no pressure should be applied to the
