It is possible to adjust the level of window contamination (in percentage) required to produce an indication (I), warning (W), or alarm (A). You can adjust the limits separately for transmitter, receiver(s), and path(s).

WARNING

Contact Vaisala before changing any warning or alarm limits. If you set the contamination alarm limit too high, measurement quality may become compromised without the device reporting about the condition.

When FD70 is installed in a high-humidity environment with strong condensation, the standard heater settings may not be enough to keep FD70 windows free from condensation. In high-humidity environments, Vaisala recommends using the following settings.
0> level 2
2> set heater.hood.dtoff 17
2> set heater.hood.dton 15
To check the settings (dton and dtoff defaults are 5 and 7):
2> get heater.hood
heater.hood.mode AUTO
heater.hood.tmax 40
heater.hood.tmin 10
heater.hood.dton 15 *
heater.hood.dtoff 17 *
heater.hood.tsafe 50
heater.hood.powermode NORMAL
heater.hood.cycletime 30
