Hello Herbert, Is this circuit work for you? I found that my latest project needs this kind of circuit as well. However it requires the test to be performed under this condition: o---R---C---o OR o---R--+--C--+--o | | +--R--+ In this case, do you think the same circuit will work? I only interested in the C measurement but the R(s) must be part of the whole thing under test, and the connection points allowed is as in above (mark with an 'o'). Thanks & best regards, WH Tan -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu]On Behalf Of Herbert Graf Sent: Sunday, March 20, 2005 10:01 AM To: Microcontroller discussion list - Public.
