QLength: 1 Register (2 bytes)
QRange: +5A/ 0 A, + 150V / 0 V, +1500 W, VAR / -1500 W, VAR
QUnit: 5 / 2048 A, 150/2048 V, 1500 / 2048 W, VAR
QEach register contains a 16-bit integer. 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 complementing (inverting) all of the bits and adding 1.
The 16-bit integers have been constrained to the bounds of a signed 12-bit integer, +2047 through -
2048.
Example:
Register 53250, Phase ACurrent, might contain the following data:
Addr 53250
Value 0400H
12-bit Signed Integer (Hex) 400H
Most Significant Bit 0
12-bit Signed Integer (Decimal) +1024

Register 53256, Total Watt, might contain the following data:
Addr 53256
Value FC00H
12-bit Signed Integer (Hex) C00H
Most Significant Bit 1
Complement 3FFH
Increment 400H
