MAXQ3183 Maxim, MAXQ3183 Datasheet - Page 80

• Manufacturer Part Number: MAXQ3183
• Description: The MAXQ3183 is a dedicated electricity measurement front-end that collects and calculates polyphase voltage, current, power, energy, and many other metering and power-quality parameters of a polyphase load
• Manufacturer: Maxim

Low-Power, Multifunction, Polyphase AFE
with Harmonics and Tamper Detect
This register determines whether the NS value is averaged over previous values or whether the most recently measured
value is used directly. If the value of this register is nonzero, the NS value is averaged using the following formula:
If the value of this register is zero, NS is not averaged. The MSB of this register must be zero.
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.
