11.3 Reading high resolution registers
When data reading energy and volume (E1, E3, V1), it is possible to select the default resolution with up to 8
significant digits like on the calculator display. It is also possible to select a reading with up to 9 significant digits
(ExtraDigit), which is a ten times higher resolution than on the calculator display.
Furthermore, it is possible to read the internal high-resolution registers (“HighRes”).
Below, E1 is used as an example. The same applies to E3 and V1. E1Extra digit is the same value as E1, with just one
digit more in the resolution.
Example:
E1 = 1.234.567,8 kWh
E1ExtraDigit = 1.234.567,89 kWh
E1HighRes = 4.567.890,1 Wh
11.4 Mounting of antenna
'
All radio-based modules must have either an internal or external antenna connected.
When mounting an external antenna please ensure that the antenna cable is arranged as
shown, to prevent damage of the cable when the meter is assembled.
Before opening the meter to mount a module or an antenna, the power supply must be
disconnected.
