According to the ADE9153A datasheet, AN-1571 and UG-1247, one should be able to calibrate the B channel of the ADE9153A.
I've the ADE9153A shield as well as self-designed hardware.
Sadly a sanity check for channel B isn't possible on the shield, without cutting and adjusting the hardware.
The circuit in my design for channel B is in the screenshot below(CT is the current transformer).
So far I've been able to calibrate Channel A and the Voltage Channel without issues.
Before calibrating I check MS_STATUS_CURRENT and write 0 to BI_PGAGAIN.
If MS_STATUS_CURRENT is high I write 0x0000023 to MS_ACAL_CFG and read the contents of that register (to verify that it has 0x0000023 written).
After a 10 second delay I read MS_ACAL_BICERT which returns 0.
Afterwards I read MS_STATUS_IRQ, which always returns 0xd000 indicating "mSure is not detected" and that MS_READY is low.
When I skip the calibration I'm able to read the B channel measurement registers and scale the measurements by dividing by a constant for them to make sense.
I'd like to know if anyone else has been able use mSure on Channel B and whether I've made a mistake along the way (perhaps some config I missed?)
