RE: Hickok 533 Testing KT120 or 6550

I tried this, having seen them on this site once before. They may work for the 6550, and they say that you test a KT120 like a 6550, but they don't work for a KT120 ... which is what I need to test. With a KT120, the tube barely lights up so I guess it is way underpowered with those settings. If I hold down the button I get a maximum reading of 1100. So it seems like the pins get the power, but the juice needs increasing. I have no idea how to go about that with any safety and confidence.
