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.

The Fluke meters are considered some of the best and some can be connected to a PC. They can be expensive though.

Thanks... I'm seeing several online at various sites but I'm wondering if the info being sent to the PC isn't past tense info... I would need real time, "right now" feedback viewable as it changes on the screen...

I did glean the triplet, and Fluke cust service #'s late last night so I'll be in touch with them Monday.

Whoa. Thanks very much.
The only talking meter I've seen anyone talking about online, was one made by Omega, and is now out of production. In fact there was a blog by one buyer who had issues upon receipt of his and he let it slip he was visually impaired (not knowing that would matter), and Omega would not repair the unit for him and insisted on him ONLY returning the meter to them.... as Omega said the "talking meter" was not intended for use by blind, or visually impaired people, as such use posed a hazzard to the user... and apparently, Omega wanted no part of it at all.

I will start calling those numbers Monday and see what's up with what. thanks again.

In microbiology labs, "Quebec Colony Counters TM" used to be used to quantify microbial colonies on agar plates. These simply provided a backlit grid over which a petridish was placed. Above the dish a magnifying lens was suspended. I'm guessing, but magnification is on the order of 10X??? (don't have access to one at the momment. Would some sort of mounted magnifying lens help with visualization of read out from a conventional meter?
