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 this guide.
Among hundreds of possible experimental subjects that can be studied with the NUL-
237 sensor are: Muscle fatigue, grip strength differences between dominant and non-
dominant hands, physiological studies, psychological studies, and many more.
The hand dynamometer sensor's measurement units are:
Pound (lbs): The English system unit of mass
Kilogram (kg): The SI unit of mass
Newton (N): The SI unit of force.
Reset to zero:
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 it with a constant applied force.
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 application.
3. When your sensor has been detected, click on the hand dynamometer sensor
module box (on the left side of your screen).
4. Remove all applied force from the sensor and click reset to zero your hand
dynamometer sensor.

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 (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 mini USB charger (such as a typical cell phone charger). The WIFI-201
module will run for 60-90 minutes (depending on the sensor) without being
plugged in.
4. The WIFI-201 module can be powered directly using a mini to USB cord and
plugging it into your computer or a wall charger. Please note this function is only
available on WIFI-201 modules with the USB icon on the cover.
5. For further WIFI-201 instructions or the WIFI-201 quick start guide please visit:
www.NeuLog.com; Choose "Products" on the main menu,
then choose "WiFi Communication module".

NEULOG HAND DYNAMOMETER LOGGER SENSOR GUIDE
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 hand dynamometer sensor is based on a metal rod connected at both sides to the
force sensor hooks in a special shape called 'S' shape. A strain gauge is attached to
the metal rod and connected to a very sensitive operational amplifier.
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 voltage inside the sensor's hardware, which is converted into force by
the sensor's firmware.
Maintenance and storage:
Never submerge the NeuLog plastic body in any liquid.
Do not allow liquid into the hand dynamometer sensor's 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. The
warranty is for a period of 3 years from the date of purchase and does not cover
damage of the product caused by improper use, abuse, or incorrect storage. Sensors
with a shelf life such as ion selective probes 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.
