In the selected measurement mode (Bq/cm²), the detected
count rates (cps) are converted to area activities (Bq/cm²) using
a calibration factor entered in the device. The previously saved
background rate is automatically subtracted, so that the net ar-
ea activities are displayed here.
Press the
Info
softkey to view further information on the ongo-
ing measurement. The
Graph
function allows you to present
the change of the measured value over time graphically. The
graph runs from right to left and you always see the values of
the last 120 seconds. With
Delete
the graph can be reset and it
starts all over again. In the counter/timer mode we get a new
pixel in the graph for each elapsed cycle.
