Can you check: ?
- low current measurement function (it boats \$\mu A\$ resolution)
Low current function seems to be working fine. Most of the time i was getting max 3uA off comparing to DMM. Worst on range 0-10uA then it was a bit more off like 5uA.
- Are all channels fully isolated from each other?
Measuring resistance between negative terminals of both 32V channels i got around 76MOhms.
- noise level from fan at max load
Didn't try with high load yet, but I assume it will be the same as at the time of power up. For some it might be noisy. For me it sounds similar than my TTI power supplies.
Personally I like that bumpers. Stacks nicely with Hantek.
And Auto MDIX... Well I have bigger worries in my life, but yes, bit not up to date.
