I wanted to use the rd6006, but when I saw what it had on the output, I used an analog source. See text up.
Thanks Atlan. I finally got mine calibrated. My bench 30V/5A SMPS box was extremely noisy (200+mv sometimes higher), so I switched to a linear one that was about 50-70mv noise, but actually fed that into an RD6006 to do the settings much easier digitally vs. analog dial. Perhaps your input supply on the RD was noisy making it worse?
In any case I got it calibrated, but not after having 15V fail 3 times in a row. If I keyed in the following on the RD6006, I got the following metered at the BNC inputs: (I think these are the steps, but if not, you'll get the point)
RD Set = Actual metered V at BCN
.30 = .3006
.60 = .6004
1.50 = 1.503
3.00 = 3.001
7.5 = 7.499
15.0 = 14.97
So therefore I was naturally trying to up 15.0 to 15.03 on the RD6006 which then leveled off at 15.00x V at the BNC. But every time I did that it said calibration failed. Therefore on the final time I just let it have the values above with the 15.0V sagging just the hair, and then it calibrated just fine not trying to force an exact perfect value.
I do have some more BNC splitters and stuff coming to make this much easier in the future with cleaner more-easy-to-redo setup. But thanks again.
Hello, I get a calibration error in the last step of 15v.
See my comment above for a failure a 15V as well until I stopped trying to "perfect it".
