A diagnostic method and apparatus includes a pressure gauge member having an enclosed housing, an anode plate, a pair of cathode plates sandwiching the anode plate, an anode connector at an external surface of the gauge, and a lead connecting the anode plate to the anode connector. Each of the anode plate, pair of cathode plates, and lead are confined within the gauge housing. A power supply is provided for supplying power to the anode connector, the power supply including a positive terminal and a negative terminal. A resistor is connected to each of the positive terminal of the power supply and the anode connector of the gauge member. A pair of electromagnets are positioned adjacent the gauge member, each electromagnet having a pole piece formed therein for completing a magnetic circuit outside of the gauge. A power amplifier supplies varying power to the electromagnets, and a feedback circuit is connected to the gauge, the power supply, the said power amplifier for proportionally and selectively changing a strength of the electromagnets upon detecting an opposing change in current discharge from the gauge.
