6.2 Setting / resetting meters
Meters can be independently set to zero or all at the same time. They may be set to any desired content as well. This way you
can take over existing meter contents for newly installed devices.
Resetting
To reset meters for each value to reset the appropriate bit in the register must be set.

The active reactive power meters for the A230 arise from the configuration in 'Disp_Mode' (see chapter 7).
Setting
The same registers will be used as for meter readings.

Unit factor
x
All meter contents are unsigned 32-bit integer numbers (2 registers for each value). These values refer to the significant
numbers, which will be displayed on the display unit itself.
The unit factor is an unsigned 16-bit integer number. It is used to scale the meter contents to the appropriate physical unit and to
define the number of post decimal positions (see chapter 4.3). This factor is valid for all meter contents of a device and can't be
modified.
