Re: Smart Tweezers (ST5) or Blue Ring Tester

BTW, this the SENCORE patent dated March 2002, after LC75 V1.

Show me the link to this so called Tech paper
"The tec. paper:

"" ... The Z METERS simply charge the
capacitor, while measuring the rise in
voltage during the first microsecond after
applying the voltage. The instantaneous
v o l t a g e s t e p c a l c u l a t e s d i r e c t l y t o
resistance using normal voltage-dividing
formulas. " Sencore has been granted a
patent on this test. ..."

So the point is??? So what???
We are going in circle here. Are you going to use your tools to troubleshoot the problems or just want to have tools but really do not know how to use them properly.

Like I asked, which model is this applied too, the newer version? you already see the block diagram of my LC75 showing PULSE GENERATORS.
I also asked you to provide the link so I can read the whole context not just a snippet of what you show.

I justify All my comments ...

Please read "ESR in Capacitors TT104-4416.pdf"

"In circuit .... in the first stage ... if there is > 1 (Cap) ... it give error. 0 or something near zero.

I have a SS1 Satellite. board with 1 Cap ... 330 uF with 1,5 Ohm

We see this is wrong ..."
That is why you do not test or verify the the components that are still connected to other circuit in the board. In circuit is not reliable. So what more do you need. Why do keep asking if the tool can be used for in circuit testing, you already know the answer.

Sorry you don't understand.

In circuit and off the circuit ... the value is the same because we have 1 - ONEEEEEE CAP. 330 uF with 1,5 Ohm

I replaced the Cap ... et Voila!!!!!


My comment is: if we have > 1 cap - more than one Cap... yes it give wrong values.
I have experience in this field ... MB lots of them.

"Please read "ESR in Capacitors TT104-4416.pdf" I did after doing some searching, as I indicate, it is not applied to LC-75, it is just a patented they applied for claiming a new way of measuring ESR and it is used in later model. I also found that parent which I added to the attachment.
