Siglent SDM3045X - Enough is enough

<< < (6/21) > >>

Ringmodulator:
Looks like the specs for the 3055X-E are hard to find.
See attachment and use some fantasy...

I have not yet found a site to get the firmwareupdates from.

Ringmodulator:
Compairing the claimed accuracy of the 3045X and the 3055X-E, I can not see, how the additional digit of the 3055X-E gives any useful additional information.

Pinkus:
For my tasks, I usually don't need absolute accuracy. It is enough for me to know whether the voltage is 3,30 Volt, if it is 3.3001 or 3.3005 does not interest me.
But if I measure e.g. very small currents or resistances, then one digit more is quite informative.
And this is now the case with my SDM3045x with 5.5 digits. The new last digit is stable, thus: quite useful.
I would also not object about one more digit. For the SDM3065 there is already the possibility to extend it from 6.5 to 7.5 digits..... thus I would not mind 6,5 digits on my SDM3045x (of course, here the usefulness is questionable).

If I really needed absolute accuracy, I would of course buy a DMM with better specs than the SDM3045. But I am satisfied, though the extra digit is a nice-to-have and actually quite usable for me.

Kleinstein:
On the PC interface there should already be a 6th and maybe even 7th digit. The accuracy would not be great, but at the low end (e.g. thermal EMF measrured in the 200 mV range it is nice to resolve 1 µV or maybe even 100 nV.

With the new SW version one may have to redo the calibration. No sure how good the old calibration from the SDM3048 SW still is with different ranges.
