Kill a watt meter seems to read ~550 in four days...

The right hand 3/4" is clouded over though. I read 55 then the clouded over section starts. Test period was 96 hours on the Samsung refrigerator. Think I am testing KwH but unsure how to read it. 5.5 KwH in four days would be very good - perhaps unbelievably so though I was gone most of the time.  Almost any other interpretation seems crazy.

Probably making an operator error here.

    5.5 kWH for 4 days is a reasonable number... Perhaps it is time to get another Kill-a-Watt or similar meter.
