Need Large display DMM for biasing amps

Hi tube aficionados

The need to bias some amps accurately with an outboard meter, has my attention expressly as of late. My particular needs are for a meter whose display is either really big, or one that can be displayed onto another screen Ie., LCD, CRT, or PC.

Anyone have any knowledge of a DMM which has a large high contrasting display? Or One that can be used with a monitor or PC?

Characters over one inch for sure is definitely needed . 1.5 inches or larger would probably work fine. Accuracy of the meter function of course, is important too.

Any suggestions in this regard would be a big, big, help.

Thanks very much.

Thank you Blindjim for all the excellent info. As I have graduated to pure non visual UI two and a half decades ago, I am intrigued by the Fluke with USB capability. I would interface with the ICON talking PDA, which is all based on LINUX and Python. If you were interested in this little beauty, you will find info at:

Sounds good BlindJim, let me know how the quest goes. . . there are many ways to skin this particular cat. Ghosthouse, yes there are dedicated magnifying lenses and mono/binoculars for visually impaired people. Problem with magnifying lenses is that they tend to distort the image. A better solution may be to place the display of a regular DMM under one of the many electronic magnifyiers for VIPs available from such companies as Humanware, Freedom Scientific, Optalek, Guerrilla Technologies and so forth. These things used to be Huge, but now they are sometimes smaller than a paperback book and are quite flexible in their applicability.
