The manual also says you SHOULD NOT use the Hz position with more than 30V rms, but this is for safety reasons. It doesn't say the meter will fail.
Welcome to the horror that unleaded solder is !
Unleaded solder can look very dull and almost a 'dry joint' in its appearance. I still use 2% silver loaded leaded 60/40 solder and always have nice shiny joints. Don't worry about the dull look in your meter, it is normal unleaded ROHS compliant (read 'crap') solder and should be OK. Rosin will not help as teh solder is the problem not the flux.
Kind Regards

It will damage components if you leave it connected to that high a voltage for long. Check the schematic. Far as I'm aware, that will break either the capacitors or the chip itself in pretty short order.
Anyone who does that when the manual clearly states not to be used above 30V deserves to get blown up

I think the manufacturer should put a "max 30V " next to the Hz position on the meter's front panel.
So regardless of what the manual says for the non-GS approved model, it is not safe for 1000V in any way. Without the modifications that are in the GS approved model, who really knows what the safe rating for the "standard" model is as it must be worse than CATII/600V and CATIII/300V.
Be aware that the UT61E has a different version available in Europe. It did not pass the labelled CATIV/600V CATIII/1000V ratings. The revised version is now rated at CATII/600V and CATIII/300V and has upgraded fuses and more input protection.

There's no way you'd know it's WORSE, you're not an expert and you shouldn't make any assumptions.

Either way, you guys are blowing this out of proportion. It's a f**king 55$ multimeter, nobody's gonna climb the pole outside his house to measure the transformer, 99.5% or more will probably use it at best to measure switching power supplies voltages (400v or thereabouts).
Same with the fuse talk ... complaining it's a 250v rated fuse... duh, that's what it says on the front, current measurements 250v max.
Take for example Extech ex330, the winner of Dave's 50$ meter shootout :
[...]
Yeah, I'm sure it's Cat III - 600V and CAT II - 1000V ... with cheapo glass fuses (and ALSO 250v rated maximum, while it says 600v on the front), less internal protections... But no, let's all piss on the Uni-T meter because it's not Fluke or some other brand name.
In another test with 10X the voltage of the previous to minimize burden voltage effect, the 87V was 10.05mA while the 61E 9.945mA by the way.
