Electrical data
1) The accuracy of the calculated values depends on both the opera-
ting point in accordance with the hx diagram and on the primary values
measured. The hx processor operates in the range -30°C < T < +70°C,
5% rh<F<95% rh. Values outside this range are not calculated, the last
valid value is displayed. Normal atmospheric pressure of 1013.25 mbar
is used when calculating the hx values.
