Multimeter CAT II Rating Discontinuation

(1/20) > >>

EEVblog:
I got an email from Brymen:

The followings are quoted from safety standard update edition EN61010-2-033:2019 Clause 5.1.5.101. The "CAT II rating" is not allowed anymore for multimeter.
In such kind of condition, the ratings of BM235 will need to change from "CAT II 1000V, CAT III 600V & CAT IV 300V" to only "CAT III 600V & CAT IV 300V". Its  "CAT II 1000V" rating will need to be deleted in the future.


Fungus:
I totally called it, LOL!

CosteC:
CAT I was removed some time ago too.
On other side, isn't consequence of improved DMM protection, customer ignorance and unfair far east manufacturers?

"CAT I" is useful information - it lets you know the meter won't die if you apply the rated voltage with the meter set to Ohms (for example).

(assuming a CAT rating means "meter won't die at this voltage" - something else they ought to clarify in the standard)

I agree. I am not IEC however. On other side, today it is much easier/cheaper to make well protected input.
