If so desired, use the HW4 software to configure the HF62. Complete the mechanical and electrical installation
and simply power up the HF62.
7.1 Internal menu (optional keypad and display)
IMPORTANT:

The data shown on the LC display of the HF62 as well as the internal menu are generated
exclusively by circuit 1 of the HF62 (humidity measuring circuit).

The temperature data shown on the display as well as settings and functions such as temperature
adjustment, data recording, etc. correspond to the Pt100 RTD used by circuit 1 to compensate the
effect of temperature on the humidity sensor.

Data from circuit 2 (temperature) is not shown on the display and the internal menu of this circuit
is not accessible to the user.

Both the LC display and keypad operate only when circuit 1 (humidity) is powered and the output
loop is closed.
