Default Looking for voltmeter kit

Hello all of you
I am in the process of completing the "power supply of my dream".
One of the problem i meet is the meetering.
I would like to use a digital voltmeter (those with red led). I
alwready use the LCD volmeter but i dont like them. They are way too
much sensitive to static, they dont really produce a bright display
and they dont seem to like to have volt on their input when they are
off.


LCD displays may be more viewable than LED in sunlight.

LCD displays are available with backlights for use in dim
environments.

There are both LCD and LED panel meters available but they use very
similar chipsets so I'm not sure "too much sensitive to static" would
be true for one but not the other.

Does anyone could point me to some kit for that purpose.
I have room on the face plate for two of them (5 cmx2cm)


Go to Digikey and search for "LED panel meter".

I am not sure the second one for amp would be usefull. Amp change very
rapidly and maybe there is another way to measure them.


For rapidly varying quantities nothing beats a good old analog meter.

For slowly changing quantities you need to know to 4 decimal places
nothing beats a digital meter.

Sometimes digital meters are supplemented with a bargraph type display
to show rapid changes graphically.
