6.8 Gas Values & Scaling
The driver stores all gas values after multiplying them by 100. This allows the driver to store
values in arrays with formats other than floats without losing the precision provided by the ACM
unit. This is done because some downstream devices’ and protocols cannot handle floating
point numbers. This may not suite you in which case you will need to use scaling.
These parameter keywords should be added to each CSV Map Descriptor definition.
…..Data_Array_Low_Scale, Data_Array_High_Scale, Device_Low_Scale,
Device_High_Scale…….
To store the actual values reported by the ACM unit you should use the following values :
…..Data_Array_Low_Scale, Data_Array_High_Scale, Device_Low_Scale,
Device_High_Scale…….
…..0 , 1 , 0 , 100…..
