WARNING
During measurements (fault loop, RCD), do not touch conductive accessible or
foreign parts of the tested electrical installation.
 The content of this chapter should be thoroughly familiarized with. It describes the
meter circuits, the methods of measurements and basic principles concerning
interpretation of measurement results.
 A progress bar is displayed during long measurements.
 The result of the last measurement is displayed until:
o next measurement starts,
o measurement parameters are changed,
o measurement function is changed,
o the meter is switched off.
 The last measurement can be recalled using the icon.
