No. A degree in Physics helps but not enough !
A CPS with an intermittent heat related failure mode - What ohms does it show at 68F ?
Answer : around 0.9k ohms. ??? More, less?
Question - How do I test it without heating it, to produce either infinite or zero Ohms to confirm the defect?
Maybe the heat related failure also produces a higher/lower Ohms reading at 68F ?That would be a convenient clue. No Hairdryer required.
For example - maybe the CPS components are being gradually degraded by heat cycling and a CPS with heat related intermittent failure reads lower than 850 ohms at 68F ??
I am trying to find a definitive value that correlates to heat related failure. Maybe trying too hard.
