Enclosure with UV and weather protection
After some time, outdoor mounted plastics can lose their color and quality. Therefore, all hinged cover enclosures
are made of special white polycarbonate (PC). The light-stable colorants and additives are used to achieve
optimum protection of the polymer while maintaining color stability. The titanium dioxide used is especially
developed for polycarbonate and offers excellent UV protection through the reflection of the entire light spectrum
including the UV component around 340 nm. This effectively counteracts the otherwise occurring photochemical
polymer degradation. The color intensity is preserved for a long time without fading. The material is also resistant
to cold and frost.

AZ - Automatic Zero-Point Calibration (optional)
Initial Power ON: Once the device is powered up, the Auto-zero reset will be performed multiple times in intervals
shorter than 10mins (contrary to the operational mode). This is to compensate the self-heating of the sensor and
PCB after start up and to provide accurate measurements throughout. After around 30mins, the device goes fully
into operational mode.
Transmitters equipped with the automatic zero-point correction are maintenance-free.
The auto-zero calibration electronically adjusts the transmitter to zero every 10 minutes. The function eliminates
all output signal drifts due to thermal, electronic or mechanical effects. The auto-zero adjustment takes approx. 4
seconds after which the device returns to its normal operation. During the 4 seconds correction phase, the output
and display values will freeze to the last measured value. After the zero-point correction, display values and output
signal go back into live mode.
