I had a very difficult time trying to measure the firing voltage, probably due to photons and other particles whizzing around the workbench. Typically, it was about 10-15 volts higher than the smallest measurable current where I could see any hint of glowing. The value varied from reading-to-reading.
I recall that I could not repeatedly/predictably measure currents below 100uA, because the segment would just extinguish and the current went to zero. Whenever I get my last 2 R|Z568m tubes, I'll spend more time on ionization measurements. Right now, those tubes are still waiting on a dock or tarmac to get shipped to the US. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
