"It is incorrect to use the word
"Megger" as a verb, noun or in the
plural form. [36] It is an infringement of the trademark if used in
reference to a product not made by the Megger Group or its
subsidiaries"
So, I'm supposed to use it as what, an adjective or adverb?
Probably an adjective. 'A Megger high-voltage insulation tester'. Not
that anybody does. It may be incorrect but everybody (and most books too)
talk about 'A Megger'
