User Manual VARIOluxx ► Choose the desired option. If the option "fresh air inlet" is selected, zeroing is carried out via the fresh air inlet. If you select the option "selectable", you have to make further set- tings.
User Manual VARIOluxx Charging state of the battery The battery symbol in the display indicates approximately the remaining capacity of the battery. From 2% remaining capacity, the charging indicator starts to flash red. If the instrument is not connected to the mains power supply within one minute, the analyzer switches off to prevent battery discharge.
User Manual VARIOluxx The flow rate of the gas should be within 90 ln/h. Otherwise, please check probe and filter for clogging. Check also whether there is a device alarm. Temperatures of NDIR and heating hose should be within the specified range in order to guarantee a sufficient measuring accuracy.
