ET4401 Desktop Digital Bridge?
« on: June 20, 2019, 10:36:15 am »
Hi!

Anybody bought and tried one of these things?

I'm thinking about buying one later in the Autumn!

Manual & specs here:-

Note:- It's "doc" in Word format rather than PDF so you might need to convert it or use a doc viewer!

It's an enigma that's what it is!! This thing's not fixed because it doesn't want to be fixed!!

At less than 2x the price, you can get a tweezer-sized LCR meter (LCR Research Pro 1) with similar specs (yes, also 0.2% basic!) and 100kHz.

So why bother?

And a side bonus is that you get documents written by native English speakers.

Hi!

Apart from the limitations of my eyesight, which makes reading tweezer-sized miniature displays difficult, the 10M top resistance reading is a distinct limitation when you're trying to find leakages in old equipment or oscilloscopes for example!

I have a need to measure capacitance up to a 100mF.
Also, I purchased ET4401 (0.2%, 100~10kHz, 10 points) for $230. So there is no "less than 2x" price difference

Sent them an email one month ago before acquiring an sencore lc102,  they wont provide calibration how's to ...  they ask the buyer to resend the lcr for calibration if needed   :wtf: .......   they lost a client 

I did not see many differences between et44 series and et45 series    but a huge price gap ??


Happy with my lc102,    tested 50,000uf capacitors in parallel to a whopping 200,000 uf /400 volts    loll  wow  this puppy can go up to 20 farad and 20 henrys it seems ?


Searched a few places, and Aliexpress was the least expensive for the et4410 model  shipping included
