Mantissa part
Exponent part: 0 to 3, Mantissa part: 0 to 9,999
Value represented in this format = Mantissa part × 10 to the power of (exponent part - 1)
Value Mantissa part Exponent part 10 to the power of (exponent part - 1)
0.0 to 999.9 0 to 9,999 0 0.1
1,000 to 9,999 1,000 to 9,999 1 1

Example: Integrated Power Monitor (W81) = 12,340
12,340 = Mantissa part: 1,234 (04D2 hex), Exponent part: 2 = C4D2 hex →
Example: Integrated Power Monitor (W81) = 567.8
567.8 = Mantissa part: 5,678 (162E hex), Exponent part: 0 = 162E hex →
