We see the formula desired is 2*V+9.6. The factor of 2 is called the "Correction Factor" and the 9.6 is called the "Correction Offset".
Refer to the actual sensors user manual for Correction factor and offset values. This is a simple linear formula.
6.2.2 CONVERTING AN ANALOG VOLTAGE INTO PHYSICAL UNITS
Navigate to Diagnostics/Settings/Other Inputs. You can then select Analog channel 1 or 2. After selecting the channel, it will display a
screen where you can select from predefined conversions or “user” settings where you can specify the units, scale, offset, and number
of decimal places.
These Scaling Parameters are used when converting an analog signal into physical units:
• User Scale: How to scale the signal, see the “Correction Factor” in the previous section.
• User Offset: The offset for the signal, see the “Correction Offset” in the previous section.
• User Units: Physical units for the calculation. Any automatic Imperial/Metric occurs afterward. For example, if a calculation
results in °C the number could be automatically converted to °F before display. Use DegC for °C and DegF for °F.
• User Decimals: How many decimals to display. Leaving this blank or entering 0 will display 1.256 as 1. Entering 1 will display
1.256 as 1.3. Entering 2 will display 1.256 at 1.26.
