发明名称 Dual channel capacitance measurement device
摘要 The capacitance of an unknown capacitor is determined by counting the cycles of a known frequency contained within a time gate whose time duration is determined by subtracting a gate whose length is equivalent to the stray measuring capacitance from a gate whose length is determined by the capacitance of the unknown capacitor plus the unavoidable stray measuring capacitances.
