"In such cases the circuit capacitance must be rated so much lower the further the static characteristic shall be measured free of oscillations in the sub-
normal region towards lower currents because both the inductive and negative real components of the track conductance are approximately proportional to the direct current flowing in the circuit."

I see what you mean. It even begins the next sentence with "Obviously"!
