7.1.4 Edit menu
1
The edit menu is available only for
non-calibrated meters
. After calibration of the meter,
the values can no longer be changed in the edit menu.
The status of the edit menu is indicated by a hand symbol in the display.
-
blinking hand symbol: edit mode is active, the data can be edited
-
continuously illuminated hand symbol: edit mode is deactivated, but can be
activated with a password if the password function is configured
-
no hand symbol: edit mode is deactivated and can no longer be activated
The following parameters can be changed in edit mode:
a) Voltage transformer ratio
2
VT 1
3
...999
(only integers)
b) Voltage transformer ratio
2
CT 1
3
...999
(only integers)
Note:
If the transformer factors are changed for a meter that has already registered
energy, the value of the registered energy is maintained.
The new transformer factors are applied only after the change.
c) Resolutions of the energy registers
The register resolution can be changed manually via the display control.
Possible values are:
-
direct-measuring meters: 8.0
3
, 7.1, 6.2
-
transformer meters:
secondary meter: 6.2, 5.3
3
, 4.4
primary meter: The value and unit are based on the configured
convert factors for voltage (VT) and current (CT)
according to the following table:
