This register determines whether the all other measured values in the electricity meter are averaged over time. If the
value of this register is nonzero, all measured meter values are averaged using the following formula:
If the value of this register is zero, no averaging is performed. The MSB of this register must be zero.
This register specifies the b
The MSB of this register must be zero.
