Hi, Hal!
Don't know the answers to your specific questions, but many
meters are accurate to +/- 10% of full scale. The Bird is 5%.
The closer the power you are trying to read is to a significant
place on the meter, the more accurate it probably is.

I used to agravate a friend who had a Heathkit 2-meter rig and
the Heath wattmeter. He was trying to measure output of the 25
watt rig on the 250 watt scale. I pointed out that +/- 10% of
full scale was +/- 25 watts of error. Therefore a registered
output of zero to 50 watts would fall within the accuracy range
of the meter.
