internal memory chip inside the D-sub connector that includes the model and serial number of the
sensor as well as calibra"on informa"on. The ILT2400 will have the ability to read the smart detector
informa"on and apply the proper calibra"on factor to be used during tes"ng.
The D-sub not only receives the current generated by the sensor a er exposure to light, it also
supplies reverse 5 or 9 volt bias to sensors requiring bias for power and/or to improve response "me.
The D sub connector is not limited to only measuring devices manufactured by ILT. Any solid state
device that generates current from 50 pA to 1 mA can be connected to the ILT2400 for measurement
of current. Please see wiring diagram below:

could exceed 1 mA of current to prevent risk of damage to the sensi"ve measurement circuitry.
6. USB Ports:
There are three USB ports on the side of the ILT2400 device
•
A:
Is used for firmware and so ware updates and
requires the use of a memory s"ck.(USB memory s"ck is not included)
•
Micro:
Inside the ILT2400 is a 4 Gb memory device for saving data. The Micro USB is used to
download stored data and to erase data from the memory device. This port can also be used
the charge the ba*ery. (USB micro cable is not supplied).
•
Mini:
Is used to charge the ba*ery and to connect to a computer allowing the ILT2400 to run
using ILT's datalight II so ware and the flash applica"on(which allows faster sampling speeds
and profiling of the rise and fall of pulsed or flashing light sources).
7. Display:
The Display is a full color
4.3" Capaci"ve TFT Touch screen display. Contact with sharp objects will
damage the display. A stylus or finger is recommended for changing seKngs on the display. Care
should be taken when packaging and storing the meter to assure no pressure is applied to the surface
