Running the Experiment
- Leave the Working and Working Sense leads (Green and Blue) connected to the working electrode
- Leave the Counter lead (Red) connected to the counter electrode
- Connect the Reference lead (White) to the counter electrode

Finally, run the experiment with the same setup parameters in Gamry Framework
Performing Analysis and Next Steps
When the experiment is complete, compare the data sets between the two runs. If there is an improvement in the measurement, consider running an Impedance Measurement on your reference electrode. This can help to confirm that the electrode needs maintenance or replacement.
The guide for Reference Electrode Care will cover the steps needed to improve the performance of the reference electrode, including changing the filling solution and changing the frit.
A Special Note for Bridge Tubes
A bridge tube, or double junction can introduce a large impedance into a system. If there is improvement in the 2-electrode experiment, and the reference electrode falls within an acceptable impedance, consider evaluating the impedance of the reference electrode with the bridge tube.
If the problem persists, gather the files from the problematic run, the 2-electrode experiment, and the calibration report and send them to email@example.com. Include a description of your experimental setup and we would be happy to suggest additional troubleshooting steps.
