Why can the power statistics socket enter the production test but fail the test?

The following aspects can be investigated:

Check if the sampling resistance and platform configuration are consistent.
Verify if the input voltage is correct, with 220V corresponding to a resistance of 560 ohms.
Confirm if 110V voltage corresponds to a resistance of 144 ohms.
Check if the layout sampling lines are too long and causing interference due to cross talk.
