Very interesting project. This model is my favorite for field use. I have not tried to do any repairs as I don’t know of any board schematics. But have had good luck doing calibration. I have

Hello-- I'll second Merchison's enthusiastic comments-- this application (VueScan) is one of the best software purchases I've ever made! 73-- Brad AA1IP

Thank you @DavidH. That answers my most important nagging question and essentially concludes this inquiry. Thanks to everyone who helped.

If that is a reply related to ykochcal, yes and if it could be determined to work in some useful to help scan the microfiche maybe if you would be willing to donate and everyone could help get it

The common mode input range of the P6046 is only 5 volts which becomes 50 volts when the x10 attenuator head is used. This is typical of other high bandwidth low voltage active probes. High voltage

For completeness, there are a couple of other things I discovered setting up my Fujitsu fi-4530C ADF scanner (Fujitsu makes high quality, fast and compact ADF units that are often inexpensive on

A commercial copying operation should be able to copy these rapidly and cheaply Robin

Thanks David. This is very educational. What range do you classify as low voltage?

Hi all, My new project is the repair of a THS710 I bought broken at a Dutch secondhand website. So far I found three problems: The screen has a 1/2" black bar at the bottom of the screen and it is

The P6046 is a low voltage differential probe and not intended for or really suitable orapplications where isolation is required. Essentially it is a high voltage differential probe with the matched

the ones for scanning film negatives have a backlight for that purpose.

I have four cabinets full of older HP microfiche and a Canon MicroPrinter. I'd love to have those scanned. The printer is one option but it isn't working as well as it should and not sure what it will

I have a few hundred microfiche, Grundig and NordMende service manuals, some Ducati parts manuals, plus a few Ford ones. I have had various full size flatbed scanners complete with transparency

Once upon a time, I scanned a $20 bill on my scanner in full subscanned resolution, and I got a humongous file, I think it was 10 or 20 Mb. The resolution was astonishing! I could see the individual

If you had to change the output of your PG506 from what the calibration routine requested, you do *not* have a valid calibration... you have just fooled the calibration routine into thinking it is

The microfiche manuals seem to be very well organized in those files. It is also likely that a lot of stuff is already available online as scans. Here is a suggestion for identifying those films with

Hi Micro, Using Exer 02 to keep a copy of cald data is a good idea , the cal data is read from nvram location starting 1e00, so in theory can recreate, except there is probably a check sum of the data

If the totalizer runs OK you should have input pulses getting through to the counter chain. Have you checked S160 which selects internal / external clocks? If external is selected that could explain

Sorry. I forgot that. http://www.hamrick.com/

Cool. I'll try out the microfiche scanner with the free trial and see if it solves my problems. Dave Casey
