2.7 Corrosion Mitigation Test
Instruments are tested for leakage current from supply power and galvanic current self- generated by the formation of electrochemical cells between dissimilar metals. Significant capacitance can form within these electrochemical cells, so charging effects are addressed by periodic current measurements which dissipate any stored energy. This test is designed to determine whether conditions exist that could degrade the housing by either process.
Test Setup:
Voltmeter/Ammeter
Cable Conductors
Zinc Reference Electrode Chilled Salt Water Tank
Instrument Breakout Cable
Instrument Teflon Liner Under Test
The Instrument Breakout Cable provides a terminal block which exposes the conductors so voltage and current can be measured from the reference electrode to each conductor while the instrument is powered or unpowered.

RSN instruments must not DC couple their electronics to their pressure cases. The minimum allowable resistance is 10 MΩ, and this resistance must remain stable with up to 50VDC of common-mode voltage between the instrument electronics and its surrounding environment. The insulation resistance meter self-limits current to safe levels, but caution should be exercised as exposed wires will have 50VDC present.
