Check if your device is doing what it should with the three circuits of this dummy cell.
A standard dummy cell, that is delivered with each PalmSens3 or PalmSens4. This dummy cell has 3 different circuits that can be used to check the behavior of the instrument:
a) a high precision 10 kOhm resistor
b) a simplified Randles (no Warburg impedance)
c) two diodes simulating a non diffusion limited redox system
