4.4 Contrast / brightness
Defines the contrast and brightness of the display
unit; the display looks like this:
SUCL
Figure 6: The Contrast/brightness menu.
1. Change the contrast using
.
2. Go to the next field using
. Change the
brightness using
.
3. Return to the Configuration menu by
pressing the
or key.
4.5 Colours
Defines the colours of the voltage and current
curves of the screens accessible by the
,
,
and
keys. The colours available are: Magenta,
Red, Dark red, Dark brown, Brown, Orange, Yellow,
Green, Dark green, Blue, Dark blue, Light grey,
Grey, Dark grey, Black. The display looks like this:
SUCO
Figure 7: The Colours menu.
1. Select the colour of the voltage curves using
.
2. Go to the next field using
. Select the
colour of the current curves using
.
3. Return to the Configuration menu by
pressing the
or key.
4.6 Calculation parameters
Determines whether or not the harmonics are used
in calculating reactive quantities (power and
energy).
SUCA
Figure 8: The Calculation parameters menu.
1. Select With harmonics or Without harmonics
using
.
- With harmonics: the harmonics are included
in the calculation of the reactive quantities.
- Without harmonics: only the fundamental is
used in the calculation of the reactive
quantities.
2. Validate using
(this validation is mandatory
for application of the parameter). The return
to the Configuration menu is immediate.
4.7 Connection
Defines the type of connection of the C.A 8230 to
the network.
SUBR
Figure 9: The Connection menu.
1. Select single-phase or balanced three-phase
using
.
- Single-phase: measurement of the phase-to-
earth voltage associated with the phase-to-
earth current of a phase.
- Balanced three-phase: measurement of the
complementary phase-to-phase voltage of
the phase of which the phase-to-earth
current is measured. This connection is used
to calculate:
. The total powers and energies of a
balanced three-phase network (W, Wh,
VAR, VARh, VA, and VAh).
