If the cap rebounds between one multivibrator pulse and the next, the meter will read high at the low end (low frequency, large rebound) and low at the high end (high frequency, small rebound).
Okay. So I read a bit on DAR, which I had not heard of (that I recall). Read about Dissipation, Q, and such, but not Dielectric Absorption. I understand it as a rebound effect with the capacitor not fully dis-charging, and actually releasing voltage after dis-charge. I also read that it is a problem for sample/hold circuits. How would an unsatisfactory DAR be detrimental to the accuracy/operation of the 130?
Don't mind telling you Dave, this is getting a bit deep for me, but it is appreciated. Not a bad thing, need to exercise my brain.
