Bjoern No EFC. The moment I even put a small Voltage like 0.9 V through a 33 K resistor on pin 2 it quits oscillating. Bert In a message dated 8/9/2012 8:07:24 P.M. Eastern Daylight Time, b...@lysator.liu.se writes:
Hi Bert, So the EFC does not work at all? (or did I miss something obvious?) /Björn > The unit starts high and over 20 minutes comes down to 4.9999975 with 0 V > on the EFC.
