3.4 Analog Outputs

The ROTRONIC HW4 software enables free configuration and scaling of the analog outputs. The measured

values (humidity, temperature) and resultant calculated values can thus be assigned to the analog outputs

(Out1, Out2) and scaled at will. The output variants (current or voltage) are defined by the order code. They

may be changed at will without need to recalibrate the device.

Default scaling of the outputs ex works:

Output

Scale

Output 1 (Out1)

0…100 %RH

Output 2 (Out2)

-40…60 °C

The scale of the output variables and assignment of the measured variables to the outputs can be changed at

will with the HW4 software. The following output variables are available to the user:

Relative humidity

Temperature

Calculated parameters

By scaling, the user can set the limits of the temperature and measurement range freely to any values between

-999 and +9,999. Temperature measurements are possible in the following units:

°C (degrees Celsius)

°F (degrees Fahrenheit)
