first of all i would like to thank all you people for helping me out till now with my problems..but still i am unable to run the project,,,..i am posting a picture with what i am trying to do so that it would be easy to understand...i have a load cell whose output is connected to the INA118 and whos output is again connected to LM311(used as an comparator). ihave a dual rail supply with +12v gnd and -12v .
so what is going wrong, i want to further drive a relay with this circuit using a MOSFET(IRF540) but i cant get there because there is still some problem with this circuit,why that comparato doesnt give output +Vsat and -Vsat...?
the IA is working Fine
Theres another thing that i want to mention i created the dual rail supply myself,,so when i put my DMM on DC mode i can see +12 regulated vtg an the leads but when i swith to AC mode for the same leads i get 24v reading on my DMM ,,,Why?
