Hi Fellow Isogeochemers,
We have figured out that a leakage current could be caused by a blown capacitor in the voltage divider board. (It's easy to test with a meter-you get no capacitance value on the faulty cap). We have ordered 50 of these so feel free to email me if you think you might need one.
