ericgibbs Well-Known Member Most Helpful Member Sep 18, 2011 #24 Why have you changed the names of the files.?? What have you named the asy file.?? and where is located.?? The left hand image you posted is not an error, double click the Vhigh = 10 and change it to 5 Did you run the original zipped files as a test ?? and did it work OK.?

L lrjaj0000 New Member Sep 18, 2011 #25 hi; I've tested your circuit and it works, but when I used my circuitry I get a constant output. I do not know why?

Click to expand... hi, I have corrected your Vhigh for U1, U2 and U3 as I explained in my post #22 and your circuit works. The Vhigh for the Internal LOGIC IC's must be set the same as your Vs supply ie: 5V EDIT: Do you know how to do that.?? Attachments AAesp08.gif 40.2 KB · Views: 295 Last edited: Sep 18, 2011

NOTE: Its now Version m2, so keep all these files together, while you are testing. Use LM331rjaj2.asc to run Attachments AAesp09.gif 38 KB · Views: 307 LM331m2.zip 40.5 KB · Views: 252

L lrjaj0000 New Member Sep 18, 2011 #29 Hi eric, Thank you already for your help I will test the circuitry tomorrow with proper values and see if I get the same value with the oscilloscope
