• Get the Dew temperature from the "Dew" column • Superheat = Actual Temperature - Dew Temperature Example: Find the superheat on a system which uses Genetron ® R-407C when the pressure at the. Use gauges to determine the pressure at the evaporator coil outlet, and a thermometer to get the actual temperature at the same point
