In the case of either over- or under-compensated probes, the compensation capacitor is adjusted until the waveform has nice, square edges. This usually takes only a very small fraction of a turn. Note that square or rectangular waves are used for probe compensation because they have both high frequency and low frequency components.

However, compensation components have to be chosen carefully. A compensation scheme can indeed improve stability, but can also lead the system to instability, depending on the choice of component values. Similarly, a compensation configuration can work for a specific load, but modifying this load can affect stability. Figure 11.
