Vaisala HMD62 - Filtering Factor; Environmental Compensation (HMD62)

2.6 Filtering Factor
If the measuring environment produces occasional exceptionally high or low readings that
need to be averaged out in the output, you can apply a filtering factor to the RH or T output
(filtering factor range: 0.001 … 1.000). The filtering factor defines the speed at which the latest
measurement is integrated into the transmitter's output. By default, the filtering factor is set to
0.500, which means that the displayed output is a 50%+50% combination of the previous
measurement and the most recent measurement. To show the latest measurement directly in
the output, set the
filtering factor to 1.000 (no filtering).
The following formula is used when calculating the output:

Environmental Compensation (HMD62)
By default, the pressure value used in HMD62 measurement calculation in 1013.2 hPa. If the
pressure of your measurement environment
diers from this, you can configure the
transmitter's pressure compensation value with the Insight PC software.
