Connect the lead to ground and initiate the hi-pot

A long time ago, I was embarrased by this situation.
A UL or CSA inspector asked to verify that the hi-
pot tester was indeed applying voltage to the EUT.
I was about to go get a high-voltage voltmeter when
the inspector simply connected the HV lead to ground
and punched the start button.
To my dismay, the hi-pot tester indicated pass!!!
The lead was open!
Well... we pulled our warehouse stock and re-tested
all units.
