NEULOG TURBIDITY LOGGER SENSOR GUIDE
Off-line experiments
(Off-line experiments are when you do not have a sensor connected directly to a
computer, tablet, smartphone, or NeuLog viewer).
Materials needed:
NUL-231 Turbidity Sensor
Cu Cuvette Lids
BAT-200 Battery Module
Materials needed to configure your offline experiment:
USB-200 Module, WIFI-201 module or VIEW-101 Module
USB to mini USB cable (included with the USB-200 module).
Procedure:
1.
To determine the experiment settings, first connect to your chosen device (PC,
Mac, tablet, smart device) and click on the “Off-line experiment” icon after the
sensor search has ended. (For more information on how to change the
experiment settings, view the quick start procedure section for your chosen
device in this document.)
2.
Connect the turbidity sensor directly to the left side of a charged BAT-200
module.
3.
When ready to collect data press the “Start/Stop” button on the turbidity sensor,
a red light will turn on for the duration of the experiment.
4.
After the experiment has concluded (the “Start/Stop” button is pressed again or
the data collection period ends) connect the sensor to your chosen device (you
can find full instructions in each device’s quick start procedure section).
5.
Open NeuLog application.
6.
Click the “Off-line experiment” icon.
7.
Click the “Load data from sensors” icon.
8.
Select which experimental data to upload (5 experimental runs can be stored at
one time on the NUL-231 turbidity sensor).
Restoring sensor’s factory default settings:
Procedure:
1.
Connect the USB-200 to a PC, Mac, tablet, or smart device.
2.
Connect the turbidity sensor to a USB-200 module (they directly plug together).
3.
Open the NeuLog application.
4.
Click the “Tools” icon.
5.
Click the “Restore sensor’s factory defaults” on the menu.
Included with the sensor:
Three plastic cuvettes with three lids
