ADE9078 - calibration (tool) -


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?

  • The ade9000 tool should be the same you need to change the sample rate (fDSP) on the constants and config tab to 4000.

    Save off sheet then modify

    Could you attach the sheet you are using so i can look at it?  and show me the number you are using and teh calculation that is not working

    Thanks Dave
