Thank´s for your help, I already recived these manual from you
;
Thank you for your manual It has the basic things to and i use the Oszi for Longer Time.

Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.

This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.

Good list of manuals. I found a very rare one and easily get. Should be promptly to download, as we must to wait hours even after confirmed payment.
It is only necessary to connect the inductor to be measured to the standard capacitor with the shortest possible leads wd manure the resultant resonant Srequency with the Model 5 9 as a grid d i p meter. Then the actual total Circuit inductance can be read Srm! t bchart OS Figure 14. . For maximum accuracy the inductor should be replaced. with a short copper strap (about 1/2 inch
'
wide,) and the new resonant Srequency or this combination determined with the Model 59. Then rind the inductance OS this latter combination from the chart OS Figure 1 4 and subtract this value Srom that: previously measured. he dirserence IS the true inductance of the inductor. Since the presence of shields, tuning slugs, etc. may seriously a r m t the value or an inductor which is to be measured, it lpay be necessary to leave the coil in place tor msasuremsnt. In this case, it will.be necessary to disconnect any tuning capacitor, tubeg,.and other capacitors associated With the coil to be measured, besore connecting the standard capacitor across the inductor. c. Measurement OS Mutual Inductance: Mutual inductance OS two coils can be meacoils in series aldsured by Sirst connecting the ing and measuring the resultant inductance as described above in Section V(b), and then connecting the two coils in series bucking and again measuring the resultant inductance. The disterence in inductance divided by rour is the mutual lnductance. * Figure 15 outlines the above procedure step by step. The use or the ~ o d e l59 permits mutual inductance measurements to be made near the actual operating Srequencies. In some circuits this may be or considerable advantage over lower Srequency measurements. Lower v a l u ~ sOS mutual inductance can be measured with the Model 59 than those possible on most low Srequency bridges.
