GE EPM 9650/9800 manual Type F9 Angle, Most significant bit

3.9: Type F9 Angle

Length: 1 Register (2 byte)

Range: +180 / -180

Unit: 0.01 degree

This register contains a 16-bit signed (2's compliment) number. Positive values have the most significant bit clear, and have the same magnitude as an unsigned integer. Negative values have the most significant bit set. The magnitude of a negative value is found by complimenting (inverting) all of the bits and adding 1.

Example:

Register 00175, Tenth second Phase A-N Voltage to Auxiliary Voltage Phase Angle, might contain the following data:

Address	00175
