Comparing the 'Canadian' LCR tweezer 'manufacturers'

And each one gives different values...

The inevitable consequence of having more than one meter.

And possible multiple test frequencies !
Then it is user error !

Want metrology grade results then buy metrology grade instruments.

It's not a metrology issue - the difference in reading capacitance is due to the DC bias level and AC amplitude used for the test causing a shift with ceramic caps.

I use SmartTweezers and they are fine in the lab, very handy.
My only gripe is you can't upgrade firmware without sending them back to the manufacturer.

Yes and no.

Multiple testfrequencies are common for a good LCR-Meter.
In most cases, the frequency will be choosed automatically.
But this is not the point.
The point is, you could measure all inductance with one meter, no problem what this concerns.
But are the measured values in every case true….no.
It depends from the construction of the inductance.
Try for example a coil for power electronics with a meter which delivers appx 1V and a few µ/mAmperes.
Or measure a coil, which core doesn´t "fit" to the the testfrequencies you can choose/will be automatically choosed.
So what is "great", what is "correct"....when the meter shows the value you expected ?
Could be difficult when testing unknown coils.

Used them both a bit over the last few months but I have still haven't had a chance to sit down with both and do a proper head to head look at them. My leaning is to the LCR Research over the other but that could be that I have used it more and is cost me more. But overall I like the menu a bit better.

I have a couple of projects I am finishing off over the next week so I will try and clear the deck for a proper play and run them side by side with some testing including the software (done virtually nil with so far).

On 'accuracy' both are more than up to bench use but not a replacement for a full blown bench LCR meter which I may or may not have been looking at over the last few weeks

Reawakening this somewhat old thread...

beanflying did you make any comparisons between the pro+ tweezers and the DE5000?  Thx
