If big capacitance values are expected, we should start with a GST
measurement first. In the GST mode all connected capacitors are measured in
parallel (C HL + C HT + C H). This way we can check if the CP TD1 is overloaded
during the measurements or not (Figure 5-23) and we can check the single
measurements. The capacitance value out of this measurement must be the
sum of the following single measurements.
