Power output not correct

[EvertDekker]

Hi,

Thanks for you library.
I'm testing it with a very simple Arduino program on an Esp32.

#include <ATM90E32.h>

#define LINE_FREQ_DEFAULT 135 //(50Hz)
#define CURRENT_GAIN_DEFAULT 11131
#define PGA_GAIN_DEFAULT 0
#define VOLTAGE_GAIN 10692

ATM90E32 energy_meter1{};

void setup() {
  Serial.begin(115200);
  energy_meter1.begin(4, LINE_FREQ_DEFAULT, PGA_GAIN_DEFAULT, VOLTAGE_GAIN, CURRENT_GAIN_DEFAULT, CURRENT_GAIN_DEFAULT, CURRENT_GAIN_DEFAULT);
}

void loop() {
  Serial.print(energy_meter1.GetLineVoltageA());
  Serial.println(" V");
  Serial.print(energy_meter1.GetLineCurrentA());
  Serial.println(" A");
  Serial.print(energy_meter1.GetActivePowerA());
  Serial.println(" W");
  Serial.println();
  delay (3000);
}

After setting the calibration the V and A will be display correct, however the Active power is a way of.
With a 60W lightbulb connected this is my output:
228.78 V
0.26 A
1241.74 W

What's going wrong that the Active power is a factor 20 higher, but the Volt and Amp matches the expectations.
