I am a novice looking to build an LED light, not digital display, 1000v DC meter, something like a pencil type with maybe 2-3 indicator lights. It just has to indicate when the voltage is below 600v and between 600 to 1200v. I have an electrostatic sprayer that I am trying to check power supplies without the use of a voltmeter. K.I.S.S. type tool I can hand to a farmhand(understand that a voltmeter has too much going on to hand off to many employees in this field).
I have looked at the FA924 0-1000V DC Volt Meter Digital kit that is available and it would work, but a go/no go type device would be best.
Any help would be appreciated.

 

use a 1 M Ohm, 100k etc voltage divider and neon glow lamps. you could make 3 chains and adjust to some voltage where the lamp would turn on. For >1000V, you need larger 1 M Ohm resistors, not the 1/4W kind.

 

Simple schematic and parts asking too much? I have no problem with the building of it, just don't know enough to create and with what components.

 

just two resistors in series, and just any ordinary neon glow lamp.

You need 1W or 2W resistors. For instance 1 M Ohm and 82 K Ohm.
