I don't think that it should have 1 Amp input when it's not started up yet?? Unless the high-side switch is turned on 100% ...

Hi Barry,

Thanks for posting here. Can you try again with posting the image? It didn't come through for me.

Hi Barry,

Please note that the value '1' in the above image is the probe name. To find the value of any parameter please click on marker and hover the cursor over any graph as shown in below image.

Thanks and Regards,

Atul

Atul, you have come up with something that is not based on the screen shot that I showed... what happened, as I see it now, is that an unhappy coincidence of scale factors, and my confusion over traces & colours and the 'stacked' scales, made for the misinterpretation on my side... different from what you thought, but, at least I see now what happened!

The 'stacked' scales are not a great solution, it seems to me, but until I have a better idea... It seems to be less readable than an equivalent oscilloscope view, for some reason.

I think that putting the signal name at the beginning of the trace, like on a scope, would be nice?

In any case, issue is solved, thanks.
