5. Data storage
All acquired data is saved on an internal SD memory card (2GB). Data stored on the card can be read
via PC either completely or for a selectable period (manual dVISION).
All measured values will be stored as a data record at the end of each sampling interval. Dependent
on the type of sensor, the record will contain also the minimum and the maximum of a value within
an interval in addition to the interval result. The instrument saves only raw data to guarantee
traceability for quality assurance. This raw data includes also entire spectra for each sampling
interval.
For online display as well as for later generation of time distributions in dVISION, the raw data will be
interpreted with respect to the recent instrument configuration. This procedure allows a simple
retrospective analysis of data, for example if dose coefficients needs to be changed by statutory
regulations.
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. To activate the display, press the small
push button below the display. All other required inputs are realized by dynamic touch buttons on
the screen. The screen will show always the display page which has been selected before the display
was switched off. In case of a pending alert, the display turns on automatically.
6. 1. Main page
If the display wakes up the main page appears on the screen. In standby mode, this page shows the
instrument name, the name of the actual configuration (with the date of the last update) and the
selected measurement cycle. Touch the CYCLE button to call a list containing all pre-defined cycles to
select another cycle.
Now the measurement can be started by pressing the START button. It is necessary that a memory
card is inserted and a valid cycle has been selected before. All information about the status of
sampling is displayed during cycle execution:
•
Date/time (with black background if the clock needs to be set)
•
Name of the processed cycle
•
Time span from the start of the whole sampling period (total sample time)
