3.4 Power Consumption Test
This section describes how to test the current of the LGA module.
For this section, only the interface board is needed and power is provided by an
external power supply.
Before the test, you should delete the following resistors to reduce leakage current:

For interface board 30X30LGADB VER.A, delete R551.
