The peak lcr meter does do this, i watched kerry wongs review of a couple lcr meters and the all seemed to give values for D,X,Q and ESR but he never showed Z so im not sure if any meter besides peak does this.

Plenty of LCR meters do include Z. The Shannon ST42 tweezers do. The TongHui/SourceTronic 283X series do. At least some of the Instek LCRs do too. You can search for LCRZ meters or Impedance Meters too.

@OP

The LCR meters don't measure L, C nor R directly, they measure the complex voltage across DUT and complex current thru DUT, then compute the desired display parameter from such.

Almost all Bench LCRs meters show Z, some handhelds don't (like the DE-5000).

You are wrong, the DE-5000 can show Z, otherwise there would be no point in this chipset.
The DE-5000 displays much more information when connected via USB to a computer.
Here is an example of such measurements

This isn't about having a computer to read the LCR meter and computer then display results on something else, what's the point of a handheld with a computer dangling on a USB cable to read/compute/display the results!!

The DE-5000 we have can NOT DISPLAY Z , at least the DE-5000 we have.

Can anyone post an image of a DE-5000 that shows Z on it's display??

Best,

The DE-5000 can display Z as well as other important circuit parameters at a resolution not available on the built-in display when connected to a computer!!! The fact that it does not show this data on the display does not diminish its value as a full-fledged LCR meter. Whether you take advantage of these opportunities or not is up to you. I, for example, use it and I don't suffer from it at all.
