Are the calculators magnet-proof?

Post by michaelzinn » Sat Nov 30, 2019 7:36 pm

Hi.

Can I keep the calculators next to regular magnets (e.g. refrigerator magnets)? I understand that a hard drive or floppy disk would be problematic because they store data magnetically, but do the SwissMicros replicas contain anything that could be affected?

Thanks!

I'd dare to state that they are magnet-proof.

Reasoning: Data are no more stored in magnetic cores. Nor is any magnetic disk or the like implemented in this calculator. There are neither Hall sensors nor Reed relais built in. And there aren't any electron tubes like in your great-grandparents' radios or your grandparents' or parents' TV sets. Instead, all good'ol silicon electronics. No chance for static magnetism to influence anything.

So don't worry, be happy! Enjoy!

I have now tested my DM15 in some serious magnetic fields and I can confirm that:
a) the DM15 is not adversely affected by static magnetic fields of around 1T
b) the DM15 is caused to give sporadic garbled output with alternating fields (50 Hz and 400 Hz) of over 0.8 T
c) the casing screws seem to be very interesting in a static field of 8T
d) my DM15 is still working perfectly after being abused in this way.

Which is the lab you work in?
