Hi,
I had some doubts regarding the calibration process of ADE 77578.
On page 49 of the datasheet (https://www.analog.com/static/imported-files/data_sheets/ADE7758.pdf), the step 0 of gain calibration using line accumulation says that this is same as step 4 of gain calibration using pulse output. In that step 4 on page 45, there are several values which I wanted to confirm.
1) It has been written that set APCFNUM and APCFDEN to calculated value. Also it has been written that 'APCFNUM is written to 0 or 1'. But APCFNUM is a 16 bit register. So by the previous statement do you mean that all bits are either 1 or 0?
2) How do you calculate the value of MC i.e. Meter Constant?
3) Also like I(test) is the test current, similarly V(NOM) is the test voltage, right? [ I am confused by the statement 'V(NOM) is the nominal voltage at which the meter is tested'. Hence, I wanted to confirm.']
