Instrument selection review
Megger starts by checking the measurement task against range, accuracy class, environment, reporting format, and accessory needs. That review is intentionally practical. It keeps an insulation tester request from turning into a broad meter discussion, and it helps buyers avoid paying for functions that will not appear in the acceptance procedure. For power and utility teams, the review can compare insulation resistance, earth resistance, low resistance, and power quality tasks in one conversation so the selected instruments do not overlap in a confusing way.
