    4.1.1 Indication of measuring values and fault data Indication in faultless condition In normal operation the display always shows WW (Woodward). After pressing the push button <SELECT/RESET> the display switches cyclically to the next measuring value. The display can show the value as absolute or as relative value (x IN). After the measuring values had been indi- cated the setting parameters are displayed.
