I opened up my PeakTech 3725 multimeter, questionable 10A conductive tracks

hi there

Opening up my PeakTech 3725 3 1/2 digit multimeter reveals a supposedly maximum 10A conductive track of about 1.6 mm minimum width @70┬Ám thickness. I'm wondering whether this may be a little too optimistic, even for a conductive track. How high would the temperature be there in theory? On the other hand, there is only one way to find out for sure... :D

Apart from that, it actually seems a decent DMM:
-V|A|Ohms calibratable(when opened) and it gets shipped calibrated
-quiet acurate, though I haven't checked it against a calibrated device yet
-gold plated measuring contacts on the DMM, but the shipped measuring lines aren't - this is a bit of a turn off as it doesn't make much sense :|
-shielded with some metal foil (HF shielding?), but unfortunately only from the back, not the front or sides, this would make a HF-shielding pointless though :|

I'm looking forward to send some pictures for you guys in the distant future.

PeakTech does badge engineering. That is, they get their "PeakTech" badge slaped on instruments they order from manufacturers all over the world.

When you opened it, did you have an indicate who the original manufacturer of that particular meter is? Any hints on the PCB, for example?

Yeah, that's well known

I'm going to look at it as soon as I have some spare time.

Pictures please, worth 1000 words.

mikeselectricstuff:
The question is no so much whether the track can take 10A but whether it can take whatever current is needed to blow the fuse without blowing first to protect the fuse.
1.6mm seems rather puny.....
