    Concur.
    Entire texts have been writ on measuring HV.

    An approach i recall in outline from an 'amateur experimenter' type mag
    of the 1960s was to build up a Looooooooooooooong string of hi meg resistors,
    joints potted up in insulating compound, and the leads need to be carefully
    shaped to evade corona, with a milliammeter/voltmeter at the low end.

    Construction will be a challenge: the field probe may have less pitfalls.
