Click the “Load data from sensors” button.
8.
Select which experimental data to upload. (5 experimental runs can be
stored at one time on the NUL-232 UVA sensor)
Restoring sensor’s factory default settings:
Procedure:
1.
Connect the USB-200 to a PC, Mac, tablet, or smart device.
2.
Connect the UVA sensor to a USB-200 module (they directly plug together).
Please note there is no calibration required for this sensor.
3.
Open the NeuLog software.
4.
Click the “Tools” icon.
5.
Click “Restore sensor’s factory defaults” icon.
6.
If prompted to clear the graph, click either the “Off-line experiment” or “On-
line experiment” (whichever you are using).
7.
Click “Clear experiment results”.
8.
Resume from step 4.

Technical background:
The philosophy behind NeuLog’s plug and play technology is based on each sensor’s
ability to store its own data due to an internal flash memory chip and micro-controller
in each plastic NeuLog body. This technology allows the sensor to collect and then
store the digital data in the correct scientific units (
o
C,
o
F, Lux, %, ppm, for example).
The sensor is pre-calibrated at the factory. The built-in software in the logger can be
upgraded for free at any time using the provided firmware update.
The UVA sensor uses a special photodiode which reacts with electromagnetic
radiation in the UV spectrum. An internal selective filter limits the range down to
specifically the UVA range (400 to 315 nm) so only the UVA rays may pass through.
UVA rays which strike the photodiode release free electrons which generate a voltage
that can easily and accurately be measured. Voltage is converted into UVA density
easily because they are directly proportional for the known surface area which is being
measured.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the UVA sensor’s body.
After use, gently wipe away any foreign material from the UVA sensor.
Store in a box at room temperature out of direct sunlight.
