ade-7953  cf1  energymeasurement energyfrequency

 

Hello, I have a problem with an ADE7953 EVAL BOARD Z, I'm using a current sensor cct-26 with a resistor of 11 ohms for current input and a voltage divider with a relation of 1000:1 for voltage input, I want  to use the energy to frecuency converter so I can get a 50 khz signal in CF1 output, but I am having some problems with the output signal because its frequency is decreasing with time as well as current amplitude, it's decreasing slowly along time. These are the values I'm writing on calibration registers for current channel A and voltage channel.
