pm3365

The Philips PM 3365 is a 100 MHz, 100MS/s CombiScope ...

These were current when Fluke bought the scope division from Philips.

So any Fluke PM 3365 manuals would be great too!

Please contact me if you need ANY more info!

Thanks in advance!

Hi,
I'm looking for Fluke combiscope PM 3370b service manual , or schematics , the CRT display is not startup , is some strange noise from hight voltage transformer ... the hight voltage rectifier is good ... the fregvecy on hight voltage transformer is around 4,2-4,7 Khz and is not stabile ... any ideeas is well come ,

Thankyou costas
 

Hi,

Near transformer T1002 you have 3 capacitors (high voltage ones),
C1132,C1131 and C1133,you must check all for eventual short-circuit.

I hope this information is OK,i have the service manual of PM3370A and i supose
that are the same...

Let me know...

Eventualy,i can scan some pages if you need,but only the week-end.

Good luck...

Hi ,
I checked the capacitors and those are ok, it is strange that does not heat anything. if it were a short cut in transformer or somewere after that would need to heat the final line ouput transistor , I would be very helpful if you could help with some scan coppy from this area of scheme . ( final line ouput , sincroprocesor , CRT tape , mabe vertical ouput )
Thankyou and I wheit the coppy .

Hi Costas

Sorry, i made a mistake in the procedure to verify those capacitors,
you must verify,not only if are in short-circuit,but very inportant,
you should make a resistance test,for example,if you find one
with 1Mohm,change it, is not good.

Please make a resistence test of the 3 capacitors and tell me
the results,this is very important.

Saturday or sunday,i will make the scans of the circuit you need to
have the minimum information to repair the oscilloscope.

This is a good one and it deserves to be repaired.

Regards.

Hi ,:grin:you have right
I found a capacitor internal resistance 5Mohm 10nf/3kv, although the measurement with LC meter shows the good value , I've changed that now function as line ouput I think is good , frequency pulses increased to 66Khz and it is stable, strange noise disappeared , after rectifier high-voltage there, but I have nothing on screen no picture :sad:, I measured the filament of the CRT tube is good and has 18 ohm , imulsurile the filament have a maximum value of 16V and 7V effective, Mabe you have another good ideeas .... however I believe the scheme would be good that would clarify manny things ...
Thankyou again .

Hi Costas,

As promised,here is the SM (part of them,its a big book),the schematics
are in A3 format and the remaining in A4.

For information,this SM is for 7 modelsM3370A,PM3380A,PM3390A,
PM3382A,PM3384A,PM3392A and PM3394A.

If you need more information,let me know.

Have you already fixed all problems ?
Please verify,if you have pluged all the connectors,perhaps you have
forgoten to incerted one... some time it happens...

Regards

SDumas

Hi ,
The SM is realy useful , from my panel missing inductance L1131 , I put a new one and CRT started , everything is fine now .
I do not know how I can make it for your help .
Thank you

Hi Costas

No problem at all,the important is you have the oscilloscope in working
condition.
We are here to help each one.

Best regards
