I need support on the K2649. I just finished it, but the display shows the "-"sign and the leading “1” and the decimal point immediately after power up.

After app. half a minute, the display shows something “0.02”

It does not change with temperature and does not react on calibration or gain potentiometers.

I would appreciate your help.

Most likely an assembly problem.
Sorry, this forum does not allow picture uploads
If you can provide LINKS (e.g. by using a free online picture base) to HI-RES and SHARP pics of your assembly (both solder- and component side)
then we can take a look and provide some feedback.


What email address can I send the Photobucket link to?

Thanks John
