Apparently, the monitor output of my HP 339A distortion meter has some issues scaling down high voltages, which led me to incorrectly diagnose a failed output filter on this UPS, which is actually working perfectly.

I'm still uncertain as to what's caused the issue, so if anyone has any idea, do leave a comment about it.
