The reading on the local display (relative humidity or temperature) can be

display always shows the relative humidity reading. This can be changed to
temperature reading by pressing the RH/T button once. Further pressings will
change the reading between RH and T.
The temperature unit (
°
Celsius or
°
Fahrenheit) is chosen with the jumper on
back of the local display unit. For
°

position and for
°
F, it is connected to the upper position (see Figure 1).

The HMP140A series transmitters with the local
display and current output cannot be re-scaled.
