Description

Install a shunt in the RC position of J22. Rail #1 and rail #2 may experience a fault and may turn off.

Press the Store RAM to flash and accept the response.

Press and release the EVM RESET (S1) button and rail #1 can now be voltage margined.

Navigate to the GUI Monitor tab with rail #1 selected and toggle the margin window
none-low-high-none switches. Note that rail #1 voltage margins.
