This makes more sense to me.

These experiments indicate the life of the semiconductive coating, with respect to zinc loss (quantity of Zn/cm 2 divided by the dissolution rate), can be significantly extended when used with the ECU. The results of the monitoring of potential, as shown in FIG. 6, demonstrate that the test panels without the ECU have a significantly lower potential,

I spoke too soon. After a little searching, I'm inclined to think that POTENTIAL SWEEP is correct.

Here's what I see so far.

NOTE: The fact that this refers to “working electrode”, “reference electrode”, and “corrosion” makes this pretty convincing.

And here it's described as a technique:
http://corrosion-doctors.org/Dictionary/Dictionary-P.htm
Potential-sweep technique: Alternative name for voltammetry.
http://corrosion-doctors.org/Dictionary/Dictionary-V.htm
Voltammetry: An electrochemical measuring technique used for electrochemical analysis or for the determination of the kinetics and mechanism of electrode reactions. "Voltammetry" is a family of techniques with the common characteristics that the potential of the working electrode is controlled (typically with a potentiostat) and the current flowing through the electrode is measured. In one of the most common applications of the technique, the potential is scanned linearly in time; this is called the "linear-sweep voltammetry," "LSV," or "LV." "Cyclic voltammetry (CV)" is a linear-sweep voltammetry with the scan continued in the reverse direction at the end of the first scan, this cycle can be repeated a number of times.

I get the impression that the “potential sweep” technique involves “sweeping the working electrode” and then monitoring the potential of that working electrode. So “monitoring of potential" would be part of the “potential sweep” technique.

Notice that the POTENTIAL OF THE WORKING ELECTRODE IS MONITORED.

On the working electrode, oxidation or reduction reactions take place. ... The potential of the working electrode is monitored relative to the reference electrode, ... of known potential (such as a saturated calomel electrode, SCE)

[…] There are many ways to use electrochemistry as an analytical tool. One widely
used method is to let the potential of a working electrode vary linearly with time
and record the current. A result from such a linear potential sweep can be seen in
Figure 2.8. In this example, the potential of a working electrode was swept between
E1 and E2 in an electrolyte containing only the reduced form

THIS LOOKS USEFUL:
http://electrochem.cwru.edu/ed/dict.htm
look for “voltammetry”, which mentions sweeping

software was used for recording of potential sweeps, monitoring of the
potential difference between the two reference electrodes

In cyclic voltammetry (CV), the potential of the working electrode is swept over some range range while the cell current is monitored
