I am looking for a way to test a neon sign to determine the correct power supply size.
The power supplies come in a variety of different sizes but the most common are:
6kV and 10kV and a working frequency of 36-41KHz.
The power supplies are self adjusting and there is a guideline as to the amount of glass that is to be connected to them based on diameter of the tube and gas pressure.
I am looking for a solution that allows us to take the sign and measure the output of the power supply.
The idea is to be able to make sure we never load them past 80%.
We bought a Fluke Multimeter only to find out that we are limited to 1000V and do not want to destroy it in the name of progress.
What are cost effective solutions to be able to make this measurement. Will adding something like a high voltage probe work in this application with the high frequency? Or are we better off biting the bullet and purchasing something completely different?
