Der EE DE-5000 Unboxing and Teardown

<< < (24/26) > >>

Yes, but see this here...A randomly taken datasheet...

I don t have so much luck as you all i guess.
My Der EE DE-5000 is completely out of spec. I only have a Brymen 869s and those cheap lcr meter from ebay.
Every cap on my DE-5000 always give me value under those specified by alot.
For example i test a brand new cap 22uf 16v with the Brymen it gave me a value of 22.59 uf, Der EE DE-5000 gave me a value of 17.67 uf at 100hz freq. The Cheap ebay lcr gave a value of 23.21 uf.
And it is always like that.

So my question is how do i even calibrate this thing?

masterx81:
Maybe your deere is telling the truth. Cheap lcr that i've tested were simply too inaccurate. While my fluke always measure more capacitance due to really slow frequency (it measure capacitance charging and discharging che cap between 2 voltage levels and measuring the time taken. This can go as slow as few hz).
You need to measure a cap that you have the dstasheet, and check the capacitance at a given frequency. You will be surprised that the deere is spot on.

So the DE-5000 must be wrong ?

No...
For example, the brymen measures with DC only, while the DE-5000 measure with AC.
Plus you don“t know how the cheap LCR meter are measuring.
Plus you need to know, how the specs of the cap manufacturer where measured.

ROMUZ:
My DER 5000 seems quite accurate, at least for Rs.
