I would like to bench test them without the indicator gauge, even if it means making an oscillator circuit to excite the capacitor. Is there circuitry in the base of the probe? A capacitance meter displays overrange on all three wires, and an ohm meter gives different readings depending on which way you connect the leads. This implies diodes or other active components inside the probe. Any insight would be helpful.
