Error
Cell temperature does
not exceed
Potentiostat is going in
overpotential
False potential
Noisy signal
Electrolyte leackage
Possible causes
Poor contact
PTC heating element in
silicone is defect
Poor contacts
Counter electrode
Gas bubbles in front of the
reference electrode
Gas bubbles
in Haber-Luggin capillary
Impedance of the reference

Check
Check the connecting leads of the
heating elements
Measure the resistance of cold the
