The video review is here:https://www.youtube.com/watch?v=BDQBFe7GSGc
Some pictures...sorry...not the best...of the insides.

The Fluke 17B is rumored to have the same CPU IC (FS9721_LP3) as the Uni-T 90C which is 4,000 count.
The datasheet for the chip indicates 3/sec update and low battery warning is 2.4V DC.

G'Day Martin,
Great video. I've purchased a chinese 17B recently, so it was good to see a comprehensive review on the unit. Interesting compared to the International version in which there didn't seem to be a lot of difference, if any only minor. It would be intersting to see a comparo between these units and other meters of around the same value.
cheers Neville

Hi Martin,
According to the FS9271_LP3 datasheet, it takes up to 15 seconds to measure a 100uF capacitor. In your video it is not clear to me how long you waited. I suspect if the Fluke 17B couldn't read a 100uF, it would have displayed 0L.
In fact when you tested the 100uF, you can see that when you disconnected the leads at 24:43 it displayed 91.2uF briefly.

Hi Neville,
Thanks...have a just placed an order on another meter the will complete what I think will be an interesting comparison around this range and value.
I hope to do that video next week.
Cheers,
Martin.

Aaaah....thanks for pointing that out...let me nip out and check that now....
Ok, you are correct...seemed like an age but it did eventually produce a reading of 98.2uF....what I did not like was that it displayed some other arbitrary readings prior to getting to the final reading which could be misleading.
I will repeat this on camera when I do the comparison.
Thanks.

I have a question about CAT III?
In this link, http://www.fluke.com/fluke/m2en/digital-multimeters/Fluke-17B.htm?PID=75002
In "Features" the description is "CAT III 300 V". In "Specifications" the description is "CAT III measurements 600V".
The CAT III correct is 300V or 600V?
Thank you.
-
The user manual (page 12) for the 17B says CAT II 600V and CAT III 300V.
I believe the specifications tab has incorrect formatting.
