If you experience any problems with your product, please try the following troubleshooting tips before contacting the Data Harvest support team.



Loss of Bluetooth Connectivity

If the sensor loses Bluetooth connection and will not reconnect try:

Closing and reopening the EasySense 2 app.

Switching the sensor Off and then On again.

If you are using a Bluetooth Smart USB Adaptor on your computer, unplug the adaptor, plug back in again and try to reconnect.

Hard reset the sensor and then try to reconnect.

Output too high to calibrate, slow drift or unstable readings

Membrane stretched - renew membrane

Sluggish response: 

Cathode / anode in need of cleaning

Drifting or odd results:

  • If other electrochemical sensors (e.g. pH, Conductivity) are present in the same solution, they could be causing interference as they all make an electrical connection to the solution. Try removing the other sensors, moving them as far apart as possible.
  • Electrode not fully polarised - leave set up for 30 to 60 minutes and then recalibrate.
  • Water too still – move the sensor through the water or use a suitable stirrer (fish in an aquarium can make good stirrers!).
