Have just finished the kit and when powered up the display shows Low Batt and I think I’m right in assuming that the display should read in the same orientation as the wording on the PCB. If thats the case then I think I have fitted the LCD display the wrong way around.
Yes, apparantly it has been inverted.
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 like “0.02” or “0.04” or sometimes “0.06”.
It does not change with temperature and does not react on calibration or gain potentiometers.
The relay switches, when moving the potentiometer fully to the right.
What can have been gone wrong?
I would apreciate your help.
Best Regards
Albrecht Brenner
