Hi all! In Vectrex service manual you can find info about troubleshooting, one of paragraphs contains instructions to measure 5.8 KV voltage. My oscilloscope can't handle it even with 1000:1 probe which I have, my digital multimeter don't have a such large limit also. What equipment do you use for these measurements?

Neither the oscilloscope nor the multimeter can handle more than 10V?  Because the 1000:1 probe is supposed to pull the 5.8kV down to 5.8V.  Surely a meter should handle that.

Indeed, I have only 100:1 oscilloscope probe, it was a typo. I checked prices of 1000:1 probes before and found only very expensive. Now with your help I checked again, both for multimeters and oscilloscopes and there are good variants. Thanks for help!
