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.
