E41 f (T) out of range
- the temperature measurement cannot be completed. Check the temperature
sensor when only a humidity probe is used, and both temperature sensors if
also an additional temperature probe is used. Check also the temperature
measurement wires and their solderings on the component board
(TP5,TP6,TP7 and TP8 for the humidity probe and TP1, TP3 and TP4 for the
additional temperature probe). If you cannot find any faults, send the
transmitter to Vaisala for repair.
E42 f (T2) out of range
- the temperature measurement cannot be completed. Check the temperature
sensor and its solderings. Check the temperature measurement wires and their
solderings on the component board (TP5,TP6,TP7 and TP8). If you cannot
find any faults, send the transmitter to Vaisala for repair.
E43 f (Rk1 ) out of range
- the temperature measurement cannot be completed. Check the temperature
sensor and its solderings. Check the temperature measurement wires and their
solderings on the component board (TP5,TP6,TP7 and TP8). If you cannot
find any faults, send the transmitter to Vaisala for repair.
E44 f (Rk2 ) out of range
- the temperature measurement cannot be completed. Check the temperature
sensor and its solderings. Check the temperature measurement wires and their
solderings on the component board (TP5,TP6,TP7 and TP8). If you cannot
find any faults, send the transmitter to Vaisala for repair.
