2. Connect the current sensor to a USB-200 module (they directly plug
together). Please note there is no calibration required for this sensor.
3. Open the NeuLog software.
4. Click the “Tools” icon.
5. Click “Restore sensor’s factory defaults” icon.
6. If prompted to clear the graph, click either the “Off-line experiment” or “On-
line experiment” (whichever you are using).
7. Click “Clear experiment results”.
8. Resume from step 4.
Included with sensor:
 NeuLog NUL-202 Current Sensor Guide (this document).
 Power and ground wires connected directly to the sensor body.
 4mm plugs for both of the power and ground wires.

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 (
o C, o F, 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 current sensor houses both a resistor and an amplifier. As a sample is
tested the current passes through the resistor and an electric potential is measured
using an internal voltmeter. The measured potential difference is amplified and a
voltage is output. Using ohm’s law (I = V/R) the current is calculated from the known
resistance and voltage values.
Maintenance and storage:
 Never submerge the NeuLog plastic body in any liquid.
 Do not allow liquid into the current sensor’s body.
 After use, gently wipe away any foreign material from the current 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.
