East Tester ET4410 ESR Measure

<< < (7/33) > >>

indman:
Martin72,Why are you so annoyed? No one has ever given me a reasonable explanation for this device behavior.

Martin72:
I don´t think this is really an issue, it goes more in the direction couldn´t get any better.
The DE5000 is an fantastic measure device for its price - when you´re basically interested on the main values like L,C,R...
I´ve did "tons" of measures comparing to calibrated LCRs, it never fails.
The ET4410 got better accuracy, is 3-times more expensive, did some things better . but seems to have "problems" similar to the DE5000 and other cheap LCRs.
But let us see what this thread will bring more on informations, which could eventually "used" for understanding the DE5000.

TimFox:
For the quite reasonable price, my only problem with the DE-5000 is that when measuring a capacitor or inductor above its self-resonant frequency, it does not indicate negative capacitance or inductance.  For that application, I wish it had R and X (with sign) direct readout.  I learned decades ago not to trust the “minority” component’s accuracy (e.g. ESR for good capacitor) when Q > 1000 on not-super-expensive equipment.

Martin72:
Yep,
And a closer look to the "chipset" of the DE5000 offers some informations, how it works and where the limitations are.
BTW, this chipset is used by several brands, even on those who cost more than double.
When you want "more", you must pay more.

Your explanation is not convincing to me, I'm sorry. A device that claims to measure secondary parameters Q, D, ESR, tg on a par with the primary parameters and cannot be trusted to make these measurements is NOT A MEASURING DEVICE! And I don't care about the cost(price) if the manufacturer can't guarantee the real specifications.
