1. Select the options “TN, TT or “IT”, “25 or 50V”, “50Hz or
60Hz” and the reference voltage in the general settings
of the instrument (see § 5.1.4). Touch the icon.
The screen to the side (TT and IT systems) is shown
on the display. The instrument automatically carries out
the test in presence of voltage between the inputs
(shown on the display) and blocks the test in case of
voltage higher than 10V
Touch the first icon in the lower left corner to set the
measuring mode. The following screen appears on the
display:
2.
Move the slide bar reference in the position " " for
the selection of the earth measurement with
voltammetric method, in the
position for the
resistance measurement with use of optional clamp
T2100 (see § 6.7.3) or in the "" position for the
measurement of ground resistivity. Confirm the choice
by going back to the initial measurement screen.
Touch the second icon in the lower left corner to set the
tripping current of the differential switch (TT and IT
systems). The following screen appears on the display:
3. Move the slide bar reference in the position
corresponding to the value of the tripping current of the
RCD differential switch as shown in the screen to the
side. On the basis of this selection and the value of
contact voltage (25V or 50V), the instrument performs
the calculation of the limit value of earth resistance (see
§ 12.11) that will compare with the measured value in
order to provide the final positive or negative result of
the measurement.
4.
For TN systems, the instrument shows the initial
screen as in the figure to the side.
Touch the central icon to set the rated current of the
RCD. The following screen appears on the display:
