ADE9078 - calibration (tool) -

Hi,

I try to understand the the calibration tool [Rev0] because I want to write a programm to calibrate the chip.

I didn't understand the value [formula, row 30] which calculate the energy conversion constant.

If I use the calculated value I always get 0 in row 72/73 [expected active energy].

  • Hello,

    I'm experiencing the exact same situation described by Blaster, no matter what values I enter the lines 72 and 73 (from the ADE9078 calibration tool) never change. It seems to me that there are some errors in the sheet's equations and I can't compare with any documentation since the ADE9078's datasheet doesn't have as much equations a the ADE9000's datasheet/user-guide.

    Can I use the ADE9000's equations for the ADE9078 (just changing some constants as the full-scale codes and the dsp frequency)?

    Is the ADE9000 calibration tool correct enough to replicate the equations for the ADE9078?
