Resistor ID...

[tmcw]

I was changing the batteries on my multimeter, and a discoloured resistor caught my eye, and I was wondering if someone could tell me what I need to get as a replacement.

The markings appear to be as follows:

KW1
5.02 "Ohm symbol" C

I presume its 5.02 Ohms (didn't know they could make resistors so precisely?), but what about the other markings, the "C" and the "KW1"?

Is this something I should be concerned about, should I be changing the resistor as a preventative measure?

Re: Resistor ID...

Retiredcaps is the meter guru - what make/model is it?
Perhaps we can find a schematic - perhaps someone has one.
Do you have another or can you borrow another meter to test the resistor.
I thought it looked like a fusible/flameproof resistor but cant find one like it.
KW1 ? - I kilowatt - seems a bit high for the size??

Re: Resistor ID...

Can it be 1Watt?, since it is also 5.02 Ohm, it may be 1% resistor to be that precise. It is also flame proof as selldoor indicated.

Check the accuracy of the meter set to the mode that uses the resistor, compare against another meter. Odds are it's just the coating or manufacturing contamination (flux residue for example) that has degraded a bit and there's no need to replace it.

That be a 0.25% tolerance 1 watt rated custom oddball value resistor.
