Re: DM42- clock losing time

Our clowns are all right regarding short time intervals. Though when you put date and time on default display you must not wonder at people bothering about it.

Re: DM42- clock losing time

Bom dia Jose, y muito obrigado for pointing to your comprehensive investigation. I admit I've read it a year ago but didn't remember. BTW, please note you called the quartz a "high precision crystal" in your post of 2018-02-11 and didn't relativize this statement any later AFAICS.

Re: DM42- clock losing time

OK, 20ppm corresponds to 10.5 minutes per year (that's far worse than any cheap quartz watch sold nowadays). But now we must talk about the 20ppm - how do you get them? Are these crystals produced according to this spec in an industrial process? I hope so. Then, to warrant almost all crystals meetin...

... I have now scanned those into the computer and created PDF's of them. Makes for great reference. And you don't have to store them in a file or book.
I concur. Though you store them in a file anyway, don't you?

Re: DM42- clock losing time

I don't remember to see any adverts from the manufacturer concerning the precision of the clock but i might be wrong. Nor do I. Though it's not a matter of specification or advertising, it's just a matter of customer expectation. If and when you include something like an RT C in a calculator nowada...

Re: DM42- clock losing time

I can confirm that the DM42 clock has a precision in the order of minutes, not seconds. My DM42 is 11 minutes ahead of true time today - I adjusted it several months ago (sorry I didn't record that date). I concur it's a calculator, not a clock, even less a precision clock. Nevertheless (and as ment...

Thanks for your feedback so far. If I understand you all correctly, we'll leave it as is. The polling station will close tomorrow at 23:00 UTC.
