Going through a specification sheet for an engineering device, I glanced upon this phrase:
...the angular scanning range of the device is a semicircle of 300 degrees...
A semicircle is usually defined as a proper half of a circle - in mathematical terms a circle of angle 180 degrees. Clearly 300 degrees is more than a half, it is closer to being 5/6th of a circle. Is it grammatically correct to refer to non-full circles as a "semicircle", even though they are not exactly a half-circle.

I would say the word arc can be used: "an arc of 300 degrees," or perhaps: "the scanning range of the device is an angle of 300 degrees".

I presume it is clear from context that you are talking about geometric angle measure, not temperature. Thus, I would get rid of the "angular scanning range" as completely superfluous non-information. Instead, you may want to add actual information, like that it is scanning range in horizontal (or vertical) plane. Or is a sphere? Or half-sphere? Look at it from the point of view of a user of the device.

In English, the prefix semi usually partly, as in semiconscious or semiautomatic.
But it can also mean half, as in semiannually, which always refers to something that happens every half-year (twice yearly).
The word semicircle has a specific defined meaning: a half of a circle or of its circumference. (Source: New Oxford American Dictionary)
So no, semicircle cannot be used to refer to any part of a circle that isn't 180 degrees.
