ok mike!
now i sent you an email at www@radio****ces.ru  for the details of the ship and price.

read the email!

thx a lot mike!

hi mike!
did you read my last two posts?
I wait for your response!

thx

mike but there is a newest version from mine?
or the esr i bought is the last version...

i read in the specs:

ESR (Equivalent Series Resistance) of electrolytic capacitors without removing them from the circuit board


my version is the last produced??

thx

hi mike,
sorry for my delay!!
i need of the pcb with lcd how we wrote in the thread.
How we can proceed to order it?
the price now is lower respect the price ypu told me?
i wait for you response.
thx and sorry for my delay but i had some problems in this period.

thx

then i have to put only my probes and my covers.
is it correct?

hi mike,

but without the lcd display?
only the pcb?

i have changed the transistor!!!
when i will come back at home i will try to tune the device!
i hope i will solve the problem...

stay tuned ;-)

i am happy you have understood the problem.

can you tell me how to test this component?
so i can assure it is damaged.
is this the correct datasheet:   http://www.irf.com/product-info/datasheets/data/irlml6402.pdf   ?
is it a transistor?

i found it on italian store!!!!  :-)

can you confirm it's the component i found?
do you think i need others components?

mike i have done all the steps following you last post but it seems that device doesn't write the value in the eprom...now i explain to you all the steps..

i switched on the device
i put a resistor 10 ohms and the device read 11.7 ohm
i tune r15 until i read 10 ohm and switched off the device
i put a wire in the device and switched on the device for calibration and after i read "cal done".
i put a resistor of 0.49ohm and the device read 0.33ohm then i tune r15 until i read 0.49 ohm.
i switched off the device.
i put a wire in the device and switched on the device for calibration and after i read cal done.
i put a resistor of 0.60ohm and the device read 0.50 ohm then i tune r15 until i read 0.60 ohm.
i switched off the device.
i put a wire in the device and switched on the device for calibration and after i read cal done.
i put a resistor of 0.80ohm and the device read 0.78 ohm then i tune r15 until i read 0.80 ohm.
i switched off the device.

now i do again the calibration with the wire and after i tried to read all the value of the low resistor.
i put again the resistor of 0,49 ohm and i read again 0.33 ohm!!! then the value that i  tuned before didn't write in the eprom!
the same for the other resistors!!
it seems it doesn't write in the eprom!
for confirm i put the resistor 10 ohm and the device read 11.7 ohm again!!!

did you understand the problem?
it seems the device doesn't write the value in the eprom because when i tune r15 for other resistor it lost the last tune i  did.

i hope you have understood the problem.

sorry again for my english!!

thx for understood my problem with the english!!  lol

ok now it's clear...when i will come back i will do these steps!1

thx for all mike!!!

sorry but my english is poor because i speak italian!  :-)

then...

i do the calibration..after i put the 10ohms resistor and tune R15; after i switch off the device so it saves in eprom.
after i redo the calibration and i do the tune r15 with the others low resistor doing the calibration when i switch off and switch on the device.

Is it correct?

ok thx!!

then only when i put a 10ohms resistor i don't do the calibration first!
for the others low-ohms resistor i have to do the calibration first.
is it correct?
