NEULOG CHARGE LOGGER SENSOR GUIDE
NeuLog charge logger sensor
NUL-246
The NeuLog charge sensor can be used for any science experiment or activity which
can utilize charge readings such as in the fields of Physics, Electronics, Chemistry,
Biology, etc.
The sensor comes pre-calibrated so you can start experimentation right out of the box
using any of the following guides.
The NeuLog charge sensor measures electrostatic charges. It can also be used as a
highly sensitive electroscope –indicating whether a charge is positive or negative.
Just a few of the thousands of possible experimental subjects that can be done with
the NUL-246 sensors are: explore the nature of static charge, to measure both charge
and voltage, measure charge by induction, quantify the charge on a capacitor,
discover charge distribution of conducting spheres.
The charge sensor uses the following units of measure:
Nanocoulombs (nC): A coulomb is the SI derived unit of electric charge.
Millivolts (mV): A volt is the SI derived unit of electric potential.
Quick start procedure:
PC or Mac Computer
Materials needed:
NUL-246 Charge Sensor
USB-200 USB Module
A USB to mini USB cable (which comes with the USB-200)
Your charge sensor needs to be connected to a USB-200 module. The USB-200
module then connects to a computer via a USB to mini-USB cable. Please note that
you cannot plug the charge sensor directly into the computer.
Resident PC software and browser based software can be downloaded for free at
www.NeuLog.com/dowload as well as a full software user guide. Note: Make sure not
to download and install both types of software, they will conflict on the computer.
Procedure:
1. Install the NeuLog software
2. Connect the USB-200 module to the PC or Mac
3. Connect the charge sensor to the USB-200 module (they directly plug
together). Please note there is no calibration required for this sensor.
4. Open the NeuLog software.
5. Once a charge sensor logo appears on the left side of the screen the probe
has been automatically identified and you can begin experimentation.
6. If the charge sensor is not automatically identified then click the “Search for
sensors” icon to find the sensor.
7. Select the “On-line experiment” button; this will open a graph below.
8. Click on the “Module setup” button located on the charge sensor icon in the
module window to change the sensor settings if need be.
9. Click on the experiment set up button to change the experiment settings if
need be (experiment duration for example).
10. The charge sensor will give a live reading in the box to the left of the screen
while plugged in.
11. To run an experiment and collect data click “Run experiment”.
12. To end data collection early, click “Stop experiment”.
Tablet, smart phone device
Materials needed:
NUL-246 Charge Sensor
WIFI-201 WIFI module
BAT-200 Battery
Your charge sensor needs to be connected to a WIFI-201 module. The WIFI-201
module will create a closed NeuLog wifi network which will stream the NeuLog data to
a device of your choosing. Once your device is wirelessly connected to the NeuLog
network you can run experiments and collect data through a browser of your choosing.
Procedure:
1. Connect the charge sensor directly to the left side of a WIFI-201 module (no
wires required).
2. Connect a BAT-200 module to the right side of the WIFI-201 module.

3. Although not required, we recommend plugging the BAT-200 to an outlet
using a USB to micro USB charger (such as a typical cell phone charger).
The WIFI-201 module will run for 15-75 minutes (depending on the sensor)
without being plugged in.
4. For further WIFI-201 instructions or the WIFI-201 quick start guide please
visit www.NeuLog.com/download.
5. The WIFI-201 indicator lights will flash; take no action until the LED to the
far left turns blue.
6. Take your tablet or smart phone and go to the Wi-Fi settings and select the
NeuLog network which matches the WIFI module ID found on the back of
the WIFI-201 device. (NeuLogXXXX for example)
7. Give your device 1-2 minutes to connect to the WIFI-201 network.
8. Once the device is connected go to your browser and type in the website
wifi201.com into the URL bar, then wait for 30-60 seconds.
9. You will see a “Control mode” icon in the browser, click on this icon.
10. The browser will then load a new screen and begin to auto detect the
sensors, this can take a few minutes.
11. If the browser does not auto detect, select “Search for sensors”
12. Once the sensor is found you will see an icon on the left side of the screen
for the charge sensor. The icon will display data in real time.
13. To set the charge sensor’s settings click on “Module setup” button located
on the charge sensor icon on the left side of your screen.
14. To change the experimental settings click the “Experiment setup” button
(experiment duration for example).
15. To run an experiment and collect data click “Run experiment”.
Operation with NeuLog viewer
Materials needed:
NUL-246 Charge Sensor
VIEW-101 Viewing Module
BAT-200 Battery
Procedure:
1. Connect the charge sensor to the left side of the viewer.
2. Connect the BAT-200 module to the right side of the viewer.
3. The VIEW-101 will auto detect the sensor and you will see it appear on the
left side of the screen.
4. Once the sensor appears it will be monitoring data in real time.
5. To run an experiment and collect data click the run button (little green
person).
Off-line experiments
(Off-line experiments are for when you do not have a sensor connected directly to a
computer, tablet, smartphone, or NeuLog viewer).
Materials needed:
NUL-246 Charge Sensor

Materials needed to configure your offline experiment:
USB-200 USB Module or WIFI-201 WIFI module or VIEW-101 Viewing Module
A USB to mini USB cable (which comes with the USB-200)
Procedure:
1. Connect the charge sensor directly to the left side of a charged BAT-200
module.
2. When ready to collect data press the “Start/Stop” button on the charge
sensor, a red light will turn on for the duration of the experiment.
3. To change the experiment settings first connect to your chosen device (PC,
Mac, tablet, smart device) and select the “Module setup” button. (For more
information on how to change the experiment settings view quick start
procedure section for your chosen device in this document.)
4. After the experiment has concluded (when the “Start/Stop” button is pressed
again or the data collection period ends) connect the sensor to your chosen
device. (full instructions in each device’s quick start procedure section)
5. Open NeuLog software.
6. Click the “Off-line experiment” button.
7. Click the “Load data from sensors” button.

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 (oC, oF, 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.
The Neulog charge sensor houses a voltage sensor with several capacitors in series
along the input. While an electric current flows through the circuit the capacitors gain
charge until the capacitors have a charge in equilibrium with the voltage level of the
source.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the charge sensor’s body.
After use, gently wipe away any foreign material from the charge 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.
