Note : Each parameter measurement read-outs shall be made after stabilizing the components
at room ambient for 2 hours minimum, 24 hours maximum after removal from the tests.
And in case of the wetting tests, for example, moisture resistance tests, each component
shall be made wipe or dry completely before the measurement.
