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!

Diode check The high voltage diode is built-in in the same case as the HV capacitor. Unplug the oven, discharge the capacitor and remove wires tram it. With an ohmmeter set on the highest scale, measure the resistance ac ross terminal "C" and capacitor case. Reverse the meter leads and again observe the resistance reading. A normal diode should read infinite resistance in one direction and approximately 50 KQ or less when the meter leads are reversed. Note: Meters opera ted with less than 6 V battery are not adequate tor these checks. The meter should be first checked with a diode known to be good before judging a diode to be defective. Safety switches check Disconnect the oven, remove wire from terminal 1 of the switch, connect an ohmmeter to the terminals 1 and 4. With closed dOOf reading should be short circuit, with open door reading must be infinite. If reading is short circuit or infinite all the time, the switch must be replaced. 1 'I ~

Disconnect the oven, remove one wire tram the switch, connect an ohmmeter to the terminals of the switch. With open door reading has to be short circuit, with closed door reading has to be infinite. If reading is short circuit or infinite all the time switch must be replaced. Note: When replacing the failure monitor switch make sure the switch is activated when the door is open.
