Did you try more than 1 wattmeter? You could have one that is out of calibration and could be putting out more than 225 watts but you think it is less.....just a thought as to why your getting the error.

Many non-slug type meters are not that accurate at that high a power level, try another meter.

I checked with 2 Bird Wattmeters with 250 watt slug and at 100 watts with 2 100 watt slugs and error was low by a few watts between all slugs.
