muy buen manual por lo completo de este algunos esquemas estan muy divididos lo que hace algo dificil el seguimiento.
;
very good manual, with detail and clarity in esquematic diagrams and waveforms .
;
Very quality copy of original service manual, which contains the circuit diagrams, PCB and lists of components, well as recommendation for calibration procedures of device, also everything else, that need for repair, tuning and use this oscilloscope.
All presented copies have high-resolution, so you can view all in detail.
This manual will very useful for simple owners and for repairers.
I recommend these manual, because myself is owner of Philips PM3216 and I need sometimes servicing these oscilloscope (principally calibrating).
Also, these document is an example of excellent design of technical documentation.
;
Excellent printing quality.
A complete and very usefull service manual with all details.
GREAT SERVICE AT VERY LOW PRICE!

Recovery flowchart (1-1)...Changing the Vol Offset setting voltage
Note: Disregard the discharge that may appear during voltage-change setting.
[From the main flowchart (1)]
Display RST MASK 09 (light blue). / [MKS S59]
� If RST MASK 09 (light blue) is already displayed, skip this step.
B
Set VOL OFFSET to the setting value 000. / [VOF 000] � This setting becomes VOL OFFSET_min1.
Gradually increase the VOL OFFSET value until disappear the discharge (lit cell). The VOL OFFSET value must be 245 or less.
VOL OFFSET_min1
Note: Make a note of this VOL OFFSET_min1 value.
VOL OFFSET_min1
C
155?
No
Replacement of abnormal circuits or re-replacement of the panel required
Yes Display RST MASK 10 (light purple). / [MKS S60]
Set VOL OFFSET to the setting value 000. / [VOF 000] � This setting becomes VOL OFFSET_min2.
Gradually increase the VOL OFFSET value until disappear the discharge (lit cell). The VOL OFFSET value must be 245 or less.
D
VOL OFFSET_min2
Note: Make a note of this VOL OFFSET_min2 value.
VOL OFFSET_min2
155?
No
Replacement of abnormal circuits or re-replacement of the panel required VOL OFFSET_min
Yes Choose the higher value between VOL_OFFSET_min1 and VOL_OFFSET_min2, and set it as VOL_OFFSET_min.
