Re: Tektronix 465 No Trace, No Dot


 

Which should be more than enough. My Fluke 6 kilovolt high voltage
probe is only 75 megohms and it works fine for measuring cathode
voltages.

You could verify if the inverter is having a problem supplying current
to the probe by also monitoring the low voltage side at the regulator.
If the Simpson is loading the output down, then the feedback loop will
show this.

Simpson 260 VOM's provide 20 kOhms/volt sensitivity on all DC volts
ranges, as the basic meter movement is 50 microamps. A Simpson 260 with
a 5 kV range therefore provides circuit loading of 100 megohms. Many
(most?) of the 260's do not have a 5 kV range.
