I feel a bit of shame writing this thread, but I do it because I must to.
When I got those DMM units, no one came with the sort cables (banana to crocodile leads ).
I did try to measure low value capacitors 10 – 100 pF with the test leads and I failed to get any results.
And I thought that this is how those DMM act and that’s all about it.
Yesterday, a very good friend of my came to me with one fresh UNI-T 60,
so to perform to it a fast calibration check, and find out how it behaves (speed tests).
Even if this specific model did not had capacitors measuring function,
It did come with those small cables with shrouded banana and crocodiles’.
I ask from my friend to offer them to me as gift because it was not useful to him in any way.
And he did it with out a second thought. ( Thank you Sofos )
As soon he left I start testing them, so to see if they do make the difference,
and they did …
I have take pictures, the Fluke 28II has poor resolution for the job and so I added one more imaginary digit.
But even so it works !! ( at list for a rough estimation of the pF value )
The Agilent U1272A for the first time after all those months,
It did show pF with major accuracy and detail.
I feel happy and stupid, but it was not my fault,
I never got tiny leads, and never think that those high quality leads made by Fluke or other nice quality leads,
will actually block the pF measurements’!!
The sum:
My apologies to Agilent .. because I was thought that U1272A can not do that pF measurement.
My apologies to Fluke .. for the same reason.
My thanks to my friend Sofos ( donor of those UNI-T cables)
And finally I like to thanks my own curiosity, because with out it I would never realize, how important it is,
all the fresh Fluke and Agilent DMM to be shipped with this low cost accessory as
standard.
Today it looks very ridicules that they do not doing that !!
And the list that they should do , is to write this detail in the Users Manual !!
Please do it !! Or give to us the damn cables !!
