You can apply a filtering factor to the measurement output to average out measurement
output over time (for more information, see Environmental compensation and measurement
settings overview (page 114)). A default or custom filtering factor can be set using either the
local display interface or Vaisala Insight PC software.
To set a filtering factor:
1. If you are using the local display interface:
a. Select Menu > Settings > Measurement settings > Filtering.
b. To enable the default filtering factor (13 second moving average (T90)), set the
Filtering on/o selection to ON.
c. If you want to enter a custom filtering factor, set the Extended filtering on/o
selection to ON, select Filtering factor and enter the custom value with the Up and
Down buttons.
d. After the final digit, pressing Select saves the pressure value.
