Calibration

Hello,

Can you clarify how were these values acquired:

/** ADE Readings */
#define ADE_FULLSCALE_REG   5326737 /**< Max numeric value (positive/negative) corresponding to a max voltage at input */
#define ADE_FULLSCALE_VAL   0.5f /**< Max voltage at the ADC input */
#define ADE_VOLTAGE_ATT     (1.0f / 1001.0f) /**< Voltage attenuation */
#define ADE_CURRENT_FULL    49.4975f /**< Peak full scale current. Irms = 35, Ip = 35 * sqrt(2) */
#define ADE_PMAX            27059678 /**< Instantaneous power when inputs at full scale and in phase */
