MAINTENANCE Maintenance The information in this section is designed for use by qualified service personal. Service interval: Clean dust from the chassis exterior/interior and exchange filter foam based on the operating environment. Cleaning: Clean surface of the chassis with dry lintfree cloth. Use a dry velocity stream of air to clean the chassis interior. -
Page 14: Windows Updates And Antivirus/Security Software
Problematic network stacks Often intrusive IT software or network processes can interfere with the primary function of the DEWETRON system: to record data. Therefore we recommend strongly against the installation of IT/MIS software and running their processes on any DEWETRON data acquisition system, and cannot guarantee the performance of our systems if they are so configured. -

DESCRIPTION OF VOLTAGE SPECIFICATIONS Input ranges Like all measurement devices DEWETRON measurement equipment provides one or more 'Input ranges'. An 'input range' indicates the highest possible value which can be displayed, similar to the limit position of a dial instrument. -
Page 54: Common Mode Voltage
DESCRIPTION OF VOLTAGE SPECIFICATIONS If there is no measurement category specified, the measurement input is not appropriate to be applied to a public power grid. Examples: > Rated input 600 V CAT II: The measurement input can be connected to a public power grid within the category II as long as the voltage of the grid does not exceed 600 VRMS. -
Page 55: Max. Dc Voltage @Ac Coupling
DESCRIPTION OF VOLTAGE SPECIFICATIONS Max. DC voltage @AC coupling The given value refers to input AC coupled inputs only. 'Max.
