0-2 Message Type ("110" binary or 6)
 3-9 Battery voltage 8mV step measurements. Calculation: 2.7 + (value multiplied by 0.008)
 10-16 Battery current 8mA step measurements, on the range 0 to 504mA. Calculation: Multiply value by 0.008 to get battery I in Amps
 17-23 Reflection Coefficient 0 to 127 units
