1. Press the
MENU
key, move the cursor to
RCD
in the
main menu by means of the arrow keys (
,
) and
confirm with
ENTER
. Subsequently, the instrument
displays a screen similar to the one reported here to the
side.
Select
“UK” as a country (see § 5.1.2), the options “TN,
TN or IT”, “25 or 50V”, “50Hz or 60Hz” and the reference
voltage in the general settings of the instrument (see §
5.1.3).
