Some of the pictures in this manual are a bit irritating. I had to dissassemble the unit and some of the screws have different threads, which is not mentioned in this manual. Also some of the drawings of the boards look different than the actual boards.
After all, the manual was very useful. I was able to recalibrate the capstan drive and it is working fine again.

This manual is very good. 303 pages scanned in a very high resolution. My camera has bad, leaking capacitors which all of the V5000 models are suffering from these days.
There is a huge part list with all capacitors, transistors etc. in this manual which helped me a lot. Otherwise I would not have been able to buy replacement parts.
The dissassembly guide is very enormous and detailed. Unlike on the Panasonic MS1 manual I downloaded here it actually looks like the real parts look. And the screws are labeled correctly, so you shouldn't have any left after the repair. ;)

has all the schematics you could need,and very well laid out format also has all part numbers along with an exploded view which is helpful

Very nice to have! Now it is no problem to understand how it is put together.
Helps me a lot.

good scans, all is clear. all pages in order. recommended
Operating Instructions-7D15 MODES OF OPERATION Manual Stop Watch This mode uses the GATE ON OFF switches to manually turn the counter main gate on and off . The counting rate is determined by the CLOCK switches . Times of up to 10 5 s can be measured in this mode . Event Counter In the EVENTS mode, the 7D15 counters accept information from the B Input connector. The B TRIGGER 1 controls select the counter triggering point. From to . 108 events can be counted in this mode Frequency Measurements The 7D15 can measure frequencies directly from do to 225 MHz when used in the FREQ mode . To obtain greater resolution of low-frequency measurements, measure the period of the waveform and calculate frequency (Frequency = 1/Period). Frequency Ratio Measurements The ratio of one signal to another can be compared with a range of up to 104 :1 and, depending on the range, a resolution of up to 10-7 . In the Frequency Ratio mode, the "standard" or reference signal is usually connected to the EXT CLOCK IN and the signal to be compared is connected to the B Input connector.

Time Interval Measurements (TIM) Two basic modes of time interval measurements can be selected, TIM WIDTH, and TIM A-B . The TIM WIDTH mode measures the time between two points on a waveform . These points are selected by the A TRIGGER controls such that the counter main gate turns on at the point on the waveform selected by the A SLOPE and LEVEL controls and turns off at the same level but on the other slope. See Fig. 2-7c. the TIM WIDTH mode, The TIM A-B mode, like measures the time between two points on a waveform . These two points are controlled individually, such that the A TRIGGER controls select the point on the waveform that turns the main gate on, and the B TRIGGER controls select the point on the waveform that turns the main gate off. See Fig. 2-7d .
Period Measurements and Period Averaging The 7D15 measures periods from 10 ns to 10 5 s . Up to 1000 periods can be averaged to obtain a resolution of up to 10 ps . The period mode measures the time between two points on a waveform . These two points are selected by the A TRIGGER controls such that the counter main gate turns on and off at the point selected by the level and slope controls, see Fig. 2-7a . The period averaging mode holds the
