Restoring sensor’s factory default settings:
Procedure:
1.
Connect the USB-200 to a PC, Mac, tablet, or smart device.
2.
Connect the ECG 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 either” or “On-line
experiment” (whichever you are using).
7.
Click “Clear experiment results”.

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.
ECG sensors detect minor changes in electrical voltage which originate in the heart
and spread out across the body over a very short amount of time. Cells have a resting
potential of about 0.9 mV. A heart beat originates from an electrical impulse in the
Sinoatrial Node, often called the natural pacemaker. The electrical potential cascade
spreads across the heart. Using three leads, a positive, a negative, and a ground the
heart’s electrical charge (which originated in the heart) is measured.
