NEULOG BAROMETER SENSOR GUIDE
Restoring sensor’s factory default settings:
Procedure:
1. Connect the USB-200 to a PC, Mac, tablet, or smart device.
2. Connect the barometer 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.
Inside the barometer sensor’s plastic body there is a flexible membrane which bends
with atmospheric pressure differences. On one side of the membrane there is a
vacuum which is compared against the other side of the membrane, the atmosphere.
An electrical charge is generated based on the amount of flexing in the membrane.
Temperature is taken into account using internal circuitry during the pressure
calculation as to normalize the data for any thermal fluctuations.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the barometer sensor’s body.
After use, gently wipe away any foreign material from the barometer sensor.
Store in a box at room temperature out of direct sunlight.
Warranty:
We promise to deliver our sensor free of defects in materials and workmanship for a
period of 3 years from the date of purchase. Our warranty does not cover damage of
the product caused by improper use, abuse, or incorrect storage. Sensors with a shelf
life such as ion selective proves have a warranty of 1 year. Should you need to act
upon the warranty please contact your distributor. Your sensor will be repaired or
replaced.
