Accutech wireless field units have registers for Primary, Secondary and Tertiary process values. Please note that not all field unit types use all three process output values.
In general, the units for each field unit are fixed, despite the fact that you can change the units being displayed on the field unit display or in Accutech Manager. The exceptions to this are the DP10/DP20, the GL10 and the SL10, which can be used to measure different values such as Flow, Level or Pressure.
