16.6.1 Configuration data
This section explains the configuration data and calibration procedure for the Metrology
Engine. Details on the Metrology Engine interface are described in
Summarizes the Metrology Engine configuration parameters.
Table 179. Metrology Engine configuration parameters
The parameter Vpp depends on transfer of the analog input circuit in front of the
Metrology Engine and it sets the peak-to-peak range for the voltage channel (in Volt).
Examples: For 110 V mains this value will be at least 2√2 * 110 = 311 V and for 230 V
mains at least 650 V. In practice these values need to be larger, because margins for
mains voltage fluctuations and for component tolerances need to be accounted for in the
input circuit design.
The transfer of the analog input circuit in front of the Metrology Engine must guarantee
that the signal at the VOLTAGE input of the Energy Measurement IC is between V
V
The parameter I1pp for the I_HIGHGAIN input depends on transfer of the analog input
circuit in front of the Metrology Engine and it sets the peak-to-peak range for the first
current channel (in Ampere).
Example: For a single current-channel 16 A meter this value will be at least 2√2 * 16 =
45.3 A. For a two current-channel 16 A meter this range will cover the range from 0 to 1 A
and the corresponding value for I1pp will be at least 2√2 * 1 = 2.83 A. In practice the
above values need to be larger, because margins for component tolerances need to be
accounted for in the input circuit design.
The transfer of the analog input circuit in front of the Metrology Engine must guarantee
that the signal at the I_HIGHGAIN input of the Energy Measurement IC is between V
and V
