I am looking at a project where a pair of supplies drive a fluorescent display backlight. Two for bright, one for dim. To troubleshoot return units we typically remove both supplies (soldered in bricks) to test each one in turn.
Our customer is asking us to "just stick a voltmeter there" to check the output and not risk his expensive display. However, these things are outputting a 38KHz wave at some 2,000 volts.
Does anyone know of a meter or probe adaptor that can do this? I only checked Fluke but their meters only work up to some 600 v, still trying to find at what frequency. They do have a HV probe good to 40KV but only at 60 Hz.
Do meters that do both high voltage and high frequency exist?
