1 ReadIn Start reading-in the count rates. While the count rate is read in, the
average is calculated and displayed continuously. You define the
reading-in period under ReadIn Time (Device Config Setup
Cal Parameter Cal Setting).
First choose which calibration point you want to read in:
•BACKGROUND
The background radiation has to be measured so that the
detector can correctly compensate for the decay of the radia-
tion source. Before taking measurements, make sure you do
not measure any radiation from the radiation source
The easiest way to ensure this is if the source is not yet
mounted. Otherwise, close the beam path and in addition fill
the container.
•ACTIVE POINT
The count rate for the calibration point displayed under Point
No. Cal. is read in. For all calibration points, the conditions in
the container must match the conditions during operation as
closely as possible. If appropriate for your application and if it
affects the beam path, this applies, for example, to:
–Gas density
– Agitator
– Cooling/Heating jacket
Note that for a 1-point calibration, the second calibration point
is displayed only, but cannot be read-in.
When reading-in the count rates, the time remaining up to the
end of the operation is displayed. Finally, you are prompted to
confirm the measured count rate with OK. To shorten the read-
in process, you can stop any time by pressing OK.
