4B. Charging:
Charging the battery is done through the USB 3.0 mini or micro port.
WARNING: The battery pack in the UIT2400 is expected to last for many years. (up to 500 charge
cycles). Batteries should only be charged, stored and used in temperature between 0-45 degrees C,
or expansion and damage can occur. Battery packs should only be replaced by trained personnel.
Changing of the battery pack by non ILT personnel voids the warranty and can cause damage to the
pc board.
The power source can be supplied from a computer, a power bank, a charging hub, a wall-wart or any
USB 2.0 or 3.0 device. A full charge is obtained in approximately 12 - 14 hours. Meter will charges the
fastest when the power button is in the off position. The UIT2400 circuit is design to prevent over
charge. The UIT2400 has a low power indicator that will advise when the battery needs recharging.
5. Sensor Connector and Wiring:
The Smart sensors are supplied with an internal memory chip inside the D-sub connector that
includes the model and serial number of the sensor as well as calibration information.
Plug in
the sensor before turning on the UIT2400 to enable smart sensor functionality.
The D-sub not only receives the current generated by the sensor after exposure to light, it also
supplies bias to sensors requiring bias for power and/or to improve response time.
6. USB Ports:
There are three USB ports on the side of the UIT2400 device
UPDATE:
Is used for code updates and requires the use of a memory stick. (not
included)
DATA:
Accesses the internal 8GB memory device where data is saved and to charge
the battery. 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 battery.
PC:
The Mini USB port is used to connect to a computer and to charge the battery.

7. Display:
The Display is a full color
4.3" Capacitive TFT Touch screen display. Contact with sharp
objects will damage the display. A stylus or finger is recommended for changing settings on the
display. Care should be taken when packaging and storing the meter to assure no pressure is
applied to the surface of the display.
Do not expose the Heat Sources, Strong UV Sources,
liquids or Chemicals.
8. Current Measurement and Limitations:
The UIT2400 provides accurate/calibrated measurements in the 50 pico-amp to 1 milli-amp
range and can be manually fixed to a specific range, or automatically change to the correct
range as the light level changes, using the auto range feature.

Saturation
: The UIT2400 provides an autorange mechanism allowing it to measure over 8
decades of current and/or light levels. While autoranging the UIT2400 can experience
saturation. When this condition occurs the display will provide a “SATURATION” warning. To
prevent saturation, neutral density filters or apertures can be added to the sensor, or a greater
