Inrush Current when power switch moves to ON.

Hi Onx,
Can you send me the link to download firmware version 1.09.
Thanks

After struggling with the UNI-T Device Manager, I decided to try do ARB uploads directly from CSV/text file with a Python script.
The SCPI/VISA interface has several quirks, so it took longer than expected to have the details right. It now seems to work, and might be useful for others, so here it is:

EDIT: I found it.
Maybe a stupid question. Where do I update firmware? UTG962E.
Thank you.
Yuriy V.:
I have already reported above about the problem with spontaneous channel shutdowns, etc., with a simultaneous increase in the consumed current to almost 2 A and stronger heating of the generator during its operation. The reason for all this was the inrush current when turning on the generator, reaching 5-6 A (see my post above). In addition, the power switch is rated for a maximum of 3 A. As a result, over time, carbon deposits formed on the switch contacts and their resistance increased. Which led to a loss of voltage, and after some time, to a malfunction (strange behavior) of the DC-DC converter. I think that the best way to combat this phenomenon is to short-circuit the power switch terminals. Yes, this adds inconvenience, but eliminates the problem.
