If he wields it anywhere near a DB or panel board, I will rugby tackle him to the floor and smash that piece of shit with a club hammer.[/color][/font][/b]

I never said "DT830".

The Big Clive special is a "D03047" - it says so right there in the title.

"DT830" covers a million variants so I could never make a blanket statement like that.

What fake claims are those? "CAT I"??

Post #1 the input jack board markings "830B.2XB", main board "832.2" so I see it as a DT832. "DT" for Duratool? KT logo maybe Ketai. They go for less than USD $1.50 ea. in bulk  :o
With the fake "EN 61010 Cat. I 500V label" Interesting on Alibaba 99% of DT830B, DT832 etc. show a "61010" or "Cat. x" label. Farnell is getting some extra. Others majority of them jacks say 500VAC "Cat. I 250V" or others 750VAC/1,000VDC Max. which I could believe if there is proof of test.

give me a trusty test lamp any day over a digital /led testers,no battery's to go flat and they draw enough current to avoid weird ghost  readings

bit of silver paper from a fag packet across the resistor soon makes the owner  chuck em away

"DURATOOL is the registered trademark of Premier Farnell Limited"

I think it's safe to assume that they had it tested if they sell it under their brand. It is possible that they have requested some minor changes to make it pass. (Reputable EU sellers used to have their own version of some Uni-T meters with better fuses and different ratings printed on them so they would actually pass safety testing and be able to sell them legally.)

Like I said above, in this case "CAT I" almost certainly means "no overvoltage protection" (the manual, probably written by Farnell, carefully specifies "overload protection" for all modes, none of which exceeds 500V). So "CAT I 500V" is really not a very high bar. The difference in terms of clearances and insulation is something like 5x-10x compared to CAT II (aka "delicate snowflakes").

floobydust:
I thought a ripoff of Duratool Taiwan.

Cat. I 300V is a 1,500V impulse, Cat. I 600V 2,500V and there is no "500V" mains category.
Cat. II 300V spacings is 1.5mm. If the multimeter's PC board layout was done professionally, that isn't hard to achieve. But this multimeter again shows a clown car for the traces, this is why without a spacings analysis or formal testing, it's a bit scary.
EE's strive to do good but occasionally fail and this is why testing is done.

Let's see Premier Farnell provide a test certificate of any kind. That should be a good laugh.
