I have a SPD3303X-E that is hacked and if I put something like 8.000v is will say in the lower screen something like 8.003 ish. When I actually measure the voltage is is within .001 of my input value which will read 7.999 or 8.001 on the DM. It is of no concern to me since is is only about .0125%.

I have a 900KB copy for SPD3303C if anyone wants/needs it.
PM your email and I can send it.

The SPD3303X/X-E Service manual is finished and should be online soon. It's a 2MB file and if anyone is desperate for it please PM your email to me and I can send it on through.

Hi to all,
I have a problem on my SPD3303X-E power supply.
I converted to the X model.
Now I have this problem:
The power supply is no longer calibrated, I have an error of about 200mv
I lost the serial number
I am looking for the service manual to see if I can correct this problem.
I can't explain why the serial number has changed, it never happened to me.
Help is appreciated.
Best regard
Gianfranco

@ Gian2975
Yes you have made some error and maybe a recalibration might fix it. I dunno.
Got your PM so I'll email that SM to you soon.
Maybe try rolling the firmware version back to an earlier one and check for accuracy again.
Good luck.

I thank tautech for the help given to me.
Fortunately having the necessary tools I was able to perform an even more accurate calibration.
Now the last step remains, I would like to restore the serial number.
Could someone help me?
Suspicion is a command to be used under the calibration software.
Every help is appreciated
Thank you
