Question : in the large circuit schematic, there seems to be a contradiction. The configuration table for the 14V version shows R1/R5/R6 as 10/10/12k respectively. It states on the right-hand side that the schematic itself is for the 14V version, but the schematic shows the other values.
I assume the schematic is correct and the column headers in the table are swapped. Please confirm ?
- i believe you're right. The circuit seems to be for 14v output but the table's values are swaped.. u_u sry. Don't have the program installed atm to edit it, will need to do so later unless maybe can photoshop it.. eris
Question: Is the pin numbering wrong on the TL062 chip? there is a ping 11? should'nt that bee pin 8? And if you look in the datasheet http://www.datasheetcatalog.org/datasheet/stmicroelectronics/2294.pdf
The voltage is swapped. pin 8 is Vcc+ and pin 4 is Vcc-
2009/03/23 - The above mentioned images have been corrected, and a capacitor was added to improve stability in noisy environments. :D
- I cant seem to get this to work on 0-14 or 0-5v. The readings will not go low enough.

hmm, will it read but just not entirely to 0? Have you adjusted vr2 ? You may try changing the values of one of the two resistors r5 or r6..
