00hFFhDENT Instruments PowerScout 3, Serial Number, FW Rev Major Revision. Minor Revision, Scalar X
00hFFhDENT Instruments PowerScout 24, Serial number, FW Rev Major Revision. Minor Revision, Scalar {x}

00hFFh DENT Instruments PowerScout 24, PS24712001, FW Rev 1.5, Scalar 3
The 00h is used for version control and the FFh indicates the meter is active. The 00h and FFh are two
bytes in front of the string that are not displayed on the RTU.
