software.
4.1.4 Alarm Functions
Limitation of the Humidity Value
The humidity measured value can be limited to 100 %RH.
Out-of-Limits Value Alarm
Specific limit values can be defined for humidity, temperature and the calculated values; an alarm is shown
in the HW4 software when they are exceeded.
The alarm function can be enabled or disabled.
Bad Sensor Alarm
This function is a fixed component of the HM4 firmware and cannot be disabled. A short circuit at the sensor
triggers a digital alarm, which is shown in the HW4 software.
