Hi, I'm looking for a resistor to replace in place of blown one used in analog multimeter.

resistor 0.3ohm 0.2% 2W

Please see attached schematic and excerpt from parts list.
Seems Russians used to make such a high quality parts that I'm unable to find replacements even now ?

 

If you can bend a tiny bit on the tolerance:

What is the difference :

Why ohmite specifies them as 200V when they are wirewound?

The multimeeter can measure AC mains up to 3A and DC too.
The resistors need to be able to deal with 240V

Would Vishay be better then?

 

Why not get some nichrome wire and make one yourself? .3 ohms would be a quite small one(physically)

 

240V across a 0.3 ohm resistor is 800A.
It won't ever have 240V across it, but if you're still worried go with the Vishay one which says 500 Vrms for dielectric withstand.

 

That type of R is definitely nichrome wound ones.
I doubt that original has that tolerance to begin with.

 

I'd go with the higher voltage one so long as it will physically fit, however as it seems to be asociated with the 3A scale it's not going to be seeing 800A by any means.

 

Thanks everyone for your help.

I'll go with RS02BR3000FB12 vishay-dale, 3 Watts, 0.3 Ohms, 1 %

Since I have digital meeter accuracy wise it doesn't need to be super, precise. However it is still handy to measure using analog too, especially since it not made in china crap type multimeter

I should also include a 3A fuse I think, to protect it next time it would not blow if by accident I measure stronger current.

Can anyone recommend self restoring fuse for this task, forgot how they are called? Or can I use simple glass fuse?

Fast blowing glass fuse is a lot faster and will catch things better than others. They do make poly fuses that reset themselves but they're not that fast and they also introduce a lot more resistance into the circuit than a simple 1A glass one would.
