Today from Ebay . . . With user manual, remote controll manual and 4 roll of paper for the printer. Not exactly the right thing for some electronic-smd-guys. Maybe someone is interested. I have fun to play around with it :D Round about from 1988. Fully functional and precise. And from W&G you can expect a high build quality. Only the printer jammed. Has two outputs (Volts & Amps) on the rear for an oscilloscope. Direct current measurements up to 30A, voltage up to 500V. Comes with a 1000/1 A current clamp. Measures up to the 50th harmonic. 1st picture: DUT is a vacuum cleaner at full power. ~6.05A at 225V 2nd picture: Harmonics in % of the fundamental (50 Hz). Cursor is at 50 Hz. 3rd picture: DUT at ~40% power 4th picture: Overview of effective, reactive and apparent power That was only a quick play around. Have to read the friendly manual :) |

Very cool piece of equipment, any chance of a teardown. At least more pics. |

There are some interesting parts in it. I already have ~80 pics on my harddrive from a W&G SF-60 SDH/PDH jitter analyzer. But i think 80 pics are too much for the forum. I was looking for webspace and some sort of wordpress thing to show that stuff. Someday in the near future :) However, the printer now works. The shaft of the stepper drive was totally blocked with some sort of resin. A few spatter of electronics cleaner, tiny drops of oil and it works fine. |

Quality design and construction, and when there's a problem, you have a good chance to fix it. Vs. the throwaway stuff today. It's just fun to get an opportunity to work with it. |
