"The new W1 wattmeter is spec'd to provide 0.5 db accuracy.  Is this 0.5
db of full scale or of the actual reading?

If the former, then I figure that the reading at 5 watts would be plus or
minus about 1.8 watts.  If the latter, about 0.6 watts (I am not good at
doing this stuff in my head -- is this right)?"

I don't know what the FS reading of the W1 wattmeter is, but 5 watts +/-
0.5 db  would be 4.456 to 5.61 watts, or -0.544 and +0.61 watts.
