1) The standard factory setting is frost point for values below freezing. This setting can be changed to dew point with
the optional HW3 or HW4 software (except HygroPalm 1)
2) Calculation of this parameter requires barometric pressure as an input. The fixed value used for barometric
pressure can be changed either directly from the keypad (except HygroPalm 1) - see MENU, SETTINGS - or with the
optional HW3 or HW4 software (all models). The HygroPalm 3 can also be configured to accept the input from an
