General
This appendix describes how external sensors such as Accelerometer (3D), Polar HR and
GSR shall be prepared, calibrated and used in the measurement.
Getting started
Connect external signal connector box to the bipolar/module connector of the NeurOne
Amplifier.
Connect sensor cables to the external signal connector box corresponding to the markings
on the cables and connector box.
Creating the Protocol
When creating the Protocol for external sensors the following shall be noticed:
Measurement
mode
shall be
DC
Input numbers for the sensor (in Input tab of the Protocol)
o
Use Inputs 33
– 40 for external sensors
o
Check the further information how into which input sensors are connected
Range
(min; max) parameters corresponding the
Range As Calibrated
values
(=known actual min;max) on the Input tab must be measured and defined during
calibration sequence corresponding to known actual signal level (explained later in
this document). This is the goal of the calibration procedure.
Do not change Range (min=0; max=1) and Range As Calibrated
(
actual min=0;
actual max=1) parameters default values before calibration measurement
Sensor calibration
The following steps shall be performed:
Run the calibration measurement
o
Start measurement
o
Set recording on
o
Set sensor to measure known minimum level = actual min
o
Give event/trigger at the site of minimum level
o
Set sensor to measure known maximum level = actual max
