Intellitron DL-1564 reading incorrect SWR

Hi team,

Today I received a Intellitron DL-1564 15000W Dry Dummy Load under order 26091296 from Gigaparts.

It produces a SWA or well over 3. See image below showing 4.05. In fact, this small SWA meter reqisters the same level when not attached to anything. I tried every possible attachment because it does not make sense how a simple DL like this wouldn’t work.

You’ll see below I tested the SWR meter using the small DL it came with, and it reads a nice 1.01.

What am I doing wrong?
