NEULOG HAND DYNAMOMETER LOGGER SENSOR GUIDE
NeuLog hand dynamometer logger sensor
NUL-237
The NeuLog hand dynamometer sensor is useful both as a stand-alone sensor and in
conjunction with other NeuLog sensors to add a completely new dimension to
experimental data. Scientific fields which can utilize the hand dynamometer are:
Exercise science, Biology, Physiology, Psychology, etc.
The sensor comes pre-calibrated so you can start experimentation right out of the box
using any of the following guides.
Just a few of the thousands of possible experimental subjects that can be done with
the NUL-237 sensors are: Muscle fatigue, grip strength differences between dominant
and non-dominant hands, physiological studies, psychological studies, and many
more.
The hand dynamometer sensor uses the following units of measure:
Pound (lbs): The English system unit of mass
Kilogram (kg): The SI unit of mass
Newton (N): The SI unit of force
Recalibration:
The hand dynamometer sensor comes pre-calibrated however after use you may find
that the sensor is slightly off or you may want to run an experiment that requires you to
zero the sensor with a constant applied force to it.
To zero the sensor:
1. Connect the NUL-237 hand dynamometer sensor to a computer/tablet/smart
device following one of the guides below.
2. Open the NeuLog software.
3. When your sensor has been detected click on the hand dynamometer
sensor icon (on the left side of your screen)
4. Remove all applied from the sensor and click reset to zero your hand
dynamometer sensor.
5. Your hand dynamometer sensor is now recalibrated.
Note: You can zero the hand dynamometer with a constant force being applied
to it to set that value as your new “zero” .
Quick start procedure:
PC or Mac Computer
Materials needed:
NUL-237 Hand Dynamometer Sensor
USB-200 USB Module
A USB to mini USB cable (which comes with the USB-200)
Your hand dynamometer 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 hand dynamometer 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 hand dynamometer sensor to the USB-200 module (they
directly plug together).
4. Open the NeuLog software.
5. Once a hand dynamometer sensor logo appears on the left side of the
screen the probe has been automatically identified and you can begin
experimentation.
6. If the hand dynamometer 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 hand dynamometer
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 hand dynamometer 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-237 Hand Dynamometer Sensor
WIFI-201 WIFI module
BAT-200 Battery
Your hand dynamometer 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 hand dynamometer 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 hand dynamometer sensor. The icon will display data in real time.
13. To set the hand dynamometer sensor’s settings click on “Module setup”
button located on the hand dynamometer 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”.

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

NEULOG HAND DYNAMOMETER LOGGER SENSOR GUIDE
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 hand dynamometer sensor uses internal strain gauges to accurately and reliably
measure the amount of force pressing on the sensor. A low power electrical current is
run through the strain gauge. When a force is applied to the strain gauge, minor
bends and compressions add enough resistance to the current to be measured.
Lastly, the change in resistance is converted into force inside the sensors hardware.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the hand dynamometer sensor body or grip
attachment.
After use, gently wipe away any foreign material from the hand
dynamometer sensor.
Store in a box at room temperature out of direct sunlight.
Store with as little force being applied to the grip attachment as possible.
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.
Thank you for using NeuLog!
Flexible, simple, fast, forward thinking.
