So, being the adventurous type I've pulled the trigger on the Protek.

I'll be picking it up in a week and will report back with interesting pictures and such.

I did contact Protek in Korea for a manual, but they insist this item was made by a different company.  Seems odd as my research uncovered a data trail that led me right to them.  But then again, history is not an exact "science".   :-//

I doubt Protek made a lot of what they show on their website. This one looks a little too familiar: https://www.gsi-protek.com/9216a-1 - and it's hilarious that the URL for 9216B is 9216a-1. 🤣

I noticed that as well.  Specs are identical too.

An update.

So I picked up the Protec Z9218 and did some testing with a few reference capacitors.

I love the interface.  Really intuitive and I was able to find my way around it in a few minutes.  I really like the external bias feature and it some other features I really like too.  For instance you can enter the nominal value of a device and a % tolerance and do real quick go/no-go component selection.  I'm not sure if that's a common feature or not.  It is super fast and accurate below 2uF (1.999999nF or less), but when it switches to the uF range it's bonkers.  There is something really wrong in that range.  It's unable to determine ESR and shows capacitance values no where near actual - 100uF showing as 0.000787uF and 47uF showing as 0.000898uF - like I said, bonkers.  I don't know who tested this before declaring it "Fully tested and working as designed".  That's not for me to determine.

It's such a pity as it is just such a nice instrument in every other way.  Anyway, I've let the seller know and they will give me a full refund.

So, I pulled the trigger on a ET4410.  I wanted the ET4510, but I could not find a vendor that would ship to me here in Canada for some odd reason.  I was able to put them in my basket, but when I went to check out I'd get some form of "This item cannot be shipped to you location" message.  :-//

Anyway, the ET4410 should meet my needs.

What frequency were you testing the 100uF cap at? Did you do a full open/short calibration first?
