In general it means that your scale is out of calibration for one reason or another. You can try calibrating to zero, (some scales need a specific weight load for calibration - see owners manual) but if that does not work then it probably means the load cell (http://en.wikipedia.org/wiki/Load_cell) has been overloaded and usually is not repairable, however, I had a scale that read out2 and I could not re-calibrate it, so I put it in the freezer for a few hours to expand the load cell and that fixed it.
When a scale says "out2," it typically means that the weight being measured exceeds the maximum capacity of the scale. This indicates that the object being weighed is too heavy for the scale to accurately measure. To obtain an accurate reading, the object should be weighed on a scale with a higher weight capacity.
Read what the scale or the key to the scale says.
It means a balance (scale) with three beams. Triple. Beam. Balance. Exactly what it says on the tin.
It is off by 36.97%
You need to define how mean the scale points are.
The spring scale is another type of scale to measure balence.
Do you mean WHERE on the scale?
There are innumerable scales and the answer depends on which scale you mean.
Not to scale indicates something done NOT according to the proportions of an established scale of measurement
A scale weighs an object OR If you mean a scale that can be found on fish, scales can protect and animal.
Whatever the key, in the corner or side of the map says.
A scale factor is a number which scales, or multiplies, some quantity. A scale factor of two would mean to multiply whatever it is by two.
