System engineers must monitor the DC bias voltage regularly on the diagnostic terminal of the Bently Nevada 3500 rack. A shifting bias voltage typically indicates the onset of radiation fatigue in the semiconductor junction. Ensure that temperature fluctuations do not exceed +121 degC, as thermal stress accelerates radiation-induced degradation of the internal seal.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #1a365d; margin-top: 1.5rem; margin-bottom: 0.5rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eStandard PVC and Teflon cables degrade rapidly under radiation exposure, losing insulation resistance and introducing severe signal noise.

Grounding must be strictly maintained at the monitor\/rack end of the cable loop.
