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 at any time using software.
The GSR sensor uses an internal very high impedance differential
operational amplifier to convert micro changes in the skins resistance and
conductivity into measurable voltage. This voltage is sampled by the sensor
controller.
When a stimulus is sensed, the sympathetic nervous system reacts causing
many physiological changes including releasing miniscule amounts of
sweat from sweat glands. These small changes of the skin’s moisture
change the skin and tissue conductance, which is measured by the sensor.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into either the GSR sensor or probes.
Wash hands prior to use for best results.
After use, gently wipe away any foreign material from the GSR sensor.
Store in a box at room temperature out of direct sunlight.
