Fantastic videos you have been posting. Love seeing all this cool and unique test equipment and most importantly how they work and what design decisions were made.

Hi Thomas many thanks for creating this video. I did learn a few new things and I really appreciate that. About 3 years ago Tony Albus did a video on replacing the terminals from 4.2mm to 4mm and he also put a power switch on the front. I don't understand why they used a 4.2mm connectors. Rick

yes the ultra loose banana jacks are terrible, it is relevant since many experiments you could use thinn test cables for low currents, and then it could be perfectly fine to use banana leads, but you still dont like loose connections, cut the banana away and solder a proper sized screw spade open side, then you solved it real fast and easy

Wow that is some incredible 40 amp soldering technique!

Great video. Thanks for sharing. User manual reads POWER SUPPLY INPUT as AC 110V/220V ±10%，50±2Hz. Is it a typo? We at America run on 60 Hz. Please comment. Regards

it must be a typo, it will of course also work fine on 60Hz

Great video as ever. Had the unit for close on 2 years with no issue but fairly recently it stopped outputting the load to the display. Tested everything all fully and all is ok. Turns out the firmware somehow got corrupted and I don’t have a copy. Anyone got a clean version?

idea: contact the company and ask for a software upgrade and how to perform instructions, most likely they will help you.
