Yes, that is *exactly* what Bird meant. The specifications in my
Bird Model 43 Instruction Book say: "Accuracy - +/- 5% of Full Scale
Power". If *your* interpretation were correct it would say "+/- 5%
of indicated power" but it doesn't.

No, Roger is correct. Bird's specification is 5% *of full scale*.
That means the Bird's accuracy is +/- 125 Watts *anywhere* using a
2500 Watt element.
REPLY:
Total nonsense. Manufacture re specify "full scale accuracy" only
because they do not guarantee linearity and accuracy below full scale.
In other words, the accuracy is guaranteed only at full scale and
nowhere else.
By Joe and Roger's interpretation, the reading anywhere on the scale
could be off by +/- 125 watts, even at very low readings. Do you
really think that is what Bird meant? A reading of 10 watts could be
off by +/- 125 watts? Or a reading of 125 watts could actually be
zero?
