Shield must be attached to connector housing ( not tested with cable lengths over 30 meters) . Set Point for Either Pressure or Temperature For pressure, this is done by selecting a percentage of your transducer’ s full range and this will be the set point ( 40% of a 1000 PSI range will have the set point at 400 PSI) “ P40” . For temperature, simply select in degrees C where you want the set point to be ( selecting 40° C will be represented by " T40" in the part number) .
