I'm trying to measure a transient voltage with dspic. Sensor output shows that the transient continues more than 500msecs. It starts with 300mV and decays exponentially to zero in a time of 500msecs. There is no problem with a continous signal but i can't measure this transient. I only get values at the very beginning of the transient (at the first several tens of usecs.) If i try to measure in the msec region i get zero. According to the values i get, it seems that voltage decays to zero in several times of ten usecs. But sensor output on the scope view shows that it continues for atime period of ~500msecs. What may be the reason? Why can't i get correct results?
