fluke 123 keyboard is inhibited after a few hours
« on: January 01, 2016, 11:59:54 am »
buon giorno a tutti grazie per l'opportunità di scrivere nel vostro forum.
ho letto come spettatore e ho notato la vostra passione per l'elettronica.

chiederei un aiuto per riparare un fluke 123.

il difetto che presenta è che dopo l'accensione dello strumento i tasti della tastiera sono inibiti.

mi chiedevo se non fosse perchè ho cambiato la batteria dato che la sua è stata sostituita con una non originale?
se lascio in fluke senza batteria per qualche tempo si ripristina la funzione tastiera
mi scuso in aticipo per il mio inglese...grazie attendo una risposta
che ne pensate....?
gradirei un aiuto

good morning everyone thanks for the opportunity to write in your forums.
I read as a spectator and I noticed your passion for electronics.
ask help to repair a fluke 123.
the defect that presents is that after switching on the instrument keyboard keys are inhibited.
I wondered if it was because I changed the battery as its has been replaced with a non-original?
I enclose a circuit original battery that can be of help.

if I leave in fluke without battery for some time you restore the function keyboard
I apologize in advance deposit for my english ... thanks expect an answer
what do you think....?
I'd like to help

salve... :)
cerco di scrivere ancora per essere chiaro....
ipotesi che penso:
il fluke senza la batteria è come se si scaricasse qualche condensatore
infatti inserendo  la batteria tutto funziona per un periodo
dopo qualche tempo la tastiera si inibisce
lascio il fluke senza batteria per un po di tempo uno o due giorni e riprende a funzionare per qualche ora
qualcuno sa dirmi come posso intervenire
ancora grazie

Hello... :)
I included a picture of the battery changed

I try to write again to be clear ....
hypothesis that I think:
the battery is no fluke as if becomes exhausted some capacitor
In fact, everything works by inserting the battery for a period
after some time the keyboard is inhibited
I leave no fluke battery for some time a day or two and starts to work for a few hours
someone can tell me what I can do ^
thank you again

The Fluke 105B I have repaired once had trouble with the memory. It behaved irraticly with no calibration, weird characters onscreen, missing channels, keys not working etc. There where settings in the menu to reset all kind of memory settings, programs and whatever. After this and a reboot all have been working OK.
Trying is the first step towards failure

Is your fluke working on power adapter?
Lot of this meters had problem with Lead Free soldering usually on keyboard connector.
In this case is enough to re-solder this connector using some Lead Solder.
But in this case symptoms are that only part of keyboard not working.

thank you for answering ... sorry but I have been away ...... I would like you to be more precise in explaining :) :)

buon giorno a tutti,
il problema riscontrato è questo

dopo qualche minuto di funzionamento la tastiera si inibisce,come se ci fosse un blocco dei tasti. per avere il ripristino delle funzioni dei tasti devo attendere quanche giorno con batteria staccata.
vi ringrazio scusate il mio pessimo inglese
attendo che qualcuno mi dia un consiglio

good morning to all,
your problem is this
After several minutes of operation the keyboard is inhibited, as if there is a keypad lock. for the restoration of key functions have to wait quanche day with disconnected battery.
thank you excuse my bad English
I wait for someone to give me advice
