15.1. Operation and Storage
The data logger can be affected by extreme temperature and humidity conditions. Meteo-42 is designed to operate properly at temperatures between -40 and +65 °C in non-condensing environments. The display is readable between -20 and +70 °C.
On site the data logger has to be installed in a robust and weatherproof cabinet (see also at www.ammonit.com). The cabinet protects the data logger against weather and condensation damage, theft and vandalism. If humidity tolerance is exceeded and moisture penetrates, the electronics of Meteo-42 can be damaged. Users are responsible for effective humidity control.
Handle Meteo-42 with care, do not drop it, and avoid mechanical shocks and vibrations to prevent the electronics from being damaged. Do not open or break the Meteo-42 housing or any of the slots. Avoid permanent pressure on the data logger.
To ensure that Meteo-42 operates properly, install only equipment, e.g. sensors, adapters and cables, which is undamaged and approved by Ammonit. Contact Ammonit, if any questions occur.
15.2. Overvoltage / Lightning Protection
Ammonit offers lightning and overvoltage protection devices for DC and AC low-voltage supplies of components and measuring systems, ensuring protection of data and signal lines and power cables. The surge protection cable clamp is installed in the steel cabinet instead of a regular unprotected cable clamp. We offer several types of surge protection devices, differing in number of pins and voltage levels. Although the installation of overvoltage protection devices is not mandatory, we highly recommend installing them, as unprotected lightning can lead to a total breakdown of the entire measuring system. Overvoltage protection is strongly advised at freestanding measuring stations or when aircraft obstacle lights are applied.
