7–22 PQMII POWER QUALITY METER – INSTRUCTION MANUAL
CHAPTER 7: APPLICATIONS
Following the method described above:
DATA VALUE = (FF3A × 2
16
) + EA7B hexadecimal
= (65338 × 2
16
) + 60027 converted to decimal
= 4282051195 decimal
The most significant bit of the High Order register is set, therefore the Data Value is:
DATA VALUE = DATA VALUE – 2
32
= 4282051195 – 4294967296 = –12916101
Multiply the Data Value by 0.01 kW according to the Units and Scale parameter. The
resultant 3 Phase Real Power value read from the memory map is –129161.01 kW.
