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.

The DE-5000 CAN NOT DISPLAY Z, as we stated!!

Having to add another device to the DE-5000 does not diminish the fact that it CAN NOT DISPLAY Z directly!!

If one wants the Z parameter, then one must attach a USB cable to the DE-5000, then connect to a computer, then start up the computer, then a communication program and so on. This is not the same as having turn on the the DE-5000 display Z stand alone in 5~10 seconds!! The information is available within the DE-5000 but the firmware does not support displaying Z!!

Maybe the firmware will get an update and display Z and 1/Z, sure hope so, but in the meantime we'll just use our TH2830 or IM3536 when we need to display Z ;)

Best,

I don't have a TH2830 or IM3536, so I will use the DE-5000 for Z readings with a computer and USB cable if I need to examine the circuit in more detail. ;)

The DE-5000 is a great handheld, and we've said so many times!! The Special Chip Set utilized helps keep the cost down and reduces power consumption, important for a handheld, but does not perform any special measurement "magic", altho it's quite accurate as we've compared to our Lab Grade Bench LCRs many times.

Inferring that it can DISPLAY Z is wrong tho, it can't and requires a computer and cable to display Z on something other than the DE-5000 itself!!

The Special Chip Set limits the frequency range and frequency resolution, which I don't think can be improved by a firmware update. Hope to be proven wrong on this tho ;)

Best,

I have the DE-5000, it was my go to LCR for years. The Shannon ST42 retired it. Then I got the (improved) ST2832, which is superior to all of the LCRs I've ever used...and I still use the ST42 (which has Z on the tiny display). DE-5000 is nice in its own right, but it doesn't compare...especially if you need to tether it to another device for useful functionality.

tautech:
ST42 is a great device and we are to market them in NZ and showed our sample to many at the recent EMEX show in Auckland. Many were surprised such a device could offer so much capability and several firm orders were taken.

A week or so before when visiting member and buddy hendorog he got out his Agilent HH LCR meter to compare against ST42........a couple of minutes later, get me a set was the firm reply.
