Megger / Insulation Meter
"Megger" or Insulation meter - can be used to measure the isolation; for example of our 3 phase motors in the Metal Mitresaw, the Circular Table Saw or any of our normal 2 phase electric machines.
It works by putting 500V or a 1000V across the measuring probes and then checking, measuring, if the resistance is well in the mega ohms.
This means that, during measurement, there is a lethal, 1000V, across the probes !
So you must use well isolated test probes - and not hold these in your hand.
