Page 4: Applications And General Information
Aer 5400 1. Applications and general information The online continuous air sampler Aer 5400 allows the measurement of the exposure of workers and first responders with respect to radioactive aerosols. Typical application fields are nuclear facilities, the NORM industry, mines and nuclear medicine (e.g. DIN ISO 16639 / VDE 0493-1-6639). - Page 5 Aer 5400 The following picture shows the operational controls of the Aer 5400. a) Signal lights b) Air inlet c) Door-lock d) Push button to exit display standby SARAD GmbH 2023 Manual_Aer 5400_EN_27-04-2023.docx...

6. Instrument operation by menus The Aer 5400 is controlled by touch screen menus. The power consumption of the display as well as the backlight is very high compared with the other electronics. Therefore, the display will be switched off automatically after an adjustable period. The time span (max. 255 Seconds) can be set by the instrument set-up function of the operation software. -

The alert list has to be confirmed by pressing the CONFIRM button. The behaviour of the signal devices can be configured by the user for each alert source independently. Two options are available: SARAD GmbH 2023 Manual_Aer 5400_EN_27-04-2023.docx... -
Page 15: Gamma Background Compensation For The Beta Channel
If the unit with pre-set background is operated in areas without gamma radiation, the configuration needs to be changed again. Otherwise, the detection limit would be increased. To set the background count rate see the chapter "User specific settings“. SARAD GmbH 2023 Manual_Aer 5400_EN_27-04-2023.docx... -
Page 16: Dynamic Gamma Compensation, Dose Rate Measurement
The counter channel (CNT1) is configured in the manner that an average dose rate will be calculated beginning at the start of the current interval. Thus, the statistical variance will be reduced with advancing interval. SARAD GmbH 2023 Manual_Aer 5400_EN_27-04-2023.docx... -

Please note that any presented result within the stored time distribution represents always the average concentration of the period from the last filter movement to the related time stamp. The result does not represent the actual concentration in that moment. SARAD GmbH 2023 Manual_Aer 5400_EN_27-04-2023.docx... -

USB interface. The instrument offers a simple proprietary communication protocol which allows the user to access the unit by own software solutions. For more detailed information please contact the manufacturer or your retailer. SARAD GmbH 2023 Manual_Aer 5400_EN_27-04-2023.docx... -
Page 19: Alert Outputs
For example, one could use the first threshold for the dose value and the other one for Radon and Thoron concentration. In delivery state the alert is routed to the red signal light (switch output DOUT4). To disable the alert function, select the item “inactive” from the list.
