I am right there with you. I calibrated once before and it was a bit of experimenting before I got it. I have v3 hardware and needed to use "SPD3303X_1.01.01.02.05" firmware and I was able to send the commands using "EasyPower_1.01.01.18".
I recently got a more accurate benchtop meter and went to calibrate mine again. But now I am stuck on the "*CALCLS #" cleared values permanently. I can send the power supply values in Putty or EasyPower, but the voltage on my SPD3303X will not adjust after the new values are set. If I go back to the "*CALCLS #" values, it's adjustable on the whole range, but the display numbers are way off.
Maybe a caution to users, I don't know if this would have prevented it. But if you don't have to reboot after *CALCLS, then you may not need to send *CALST after clearing either. *CALST is just to store permanently. But, if you don't have to reboot after the *CALCLS, and all you have to do is change the voltage to get the cleared values. *CALST may be an unnecessary risk if you get stuck not being able to write new values.
My theory here is, if you *CALCLS, then just change the voltage on the power supply, don't just *CALST and make the cleared values permanent. If you find you can't write in new numbers, just reboot the power supply and at worst you might be back to where you started on the factory calibration. Way better than the uncalibrated values. Worth a shot if you are just starting out.
As for me, what I think happened in my case is that I saved my cal values in an Excel sheet with my voltage table. When I copied the cell, I think I copied a crlf at the end. I think that may have messed up the calibration values stored in the PS somewhere. I didn't catch the cursor dropping 1 line until I tried pasting into Putty. By then I already had sent the command in EasyPower and NI MAX.
Has anyone dug any deeper into the config table? Thinking I need a backup of a good file. Or possibly to go in and edit the config file somehow, possibly removing the crlf. Jtag maybe? Reverting firmware to all versions I have, does not fix mine.
I am quite sure it's writing. I just can't adjust voltage after I set the measured voltages. When I do the power supply is stuck on the last saved voltage I set, even after a reboot. To get it back to "somewhat functional" (but very off calibration). I need to send the *CALCLS commands, and then *CALST. Now my 1 volt is really .84. Depressing.. But, my fault too.
