Classification: CPC G | IPC G

Claim 17:
18. A method for performing an electrical stability (ES) test, the method comprising:
increasing a voltage applied to a pair of electrodes until an electrical current between the electrodes reaches a predetermined threshold, wherein the electrodes are submerged within a fluid sample within a cup, and wherein the electrodes are spaced apart from one another by a predetermined gap;
decreasing the voltage after the electrical current reaches the predetermined threshold; and
causing a wiper in the cup to pass through the predetermined gap and contact the electrodes after the voltage is decreased, wherein a width of the wiper is greater than the predetermined gap, and wherein the wiper is configured to deform as the wiper passes through the predetermined gap such that the width becomes substantially equal to the predetermined gap and sides of the wiper contact ends of the electrodes to clean the electrodes.
