3.3 Basic Parameter Setup
Before starting any measurements, you have to define the most
important parameters and change the factory-set parameters
(alarm thresholds, background, etc.) to match your needs and
circumstances.
Check and/or change the following parameters:
Set the Language.
Enter Date/Time. Important for your documentation. Date
and time are stored with each measurement.
Define Meas. Parameters for the individual measurement
modes and measurement channels in the Measuring Set-
tings menu.
If necessary, define calibration factors for additional nu-
clides or nuclide mixes and adjust the nuclide-specific warn-
ing thresholds.
Nuclide or measurement type selection for the meas-
urement. In order to select the nuclides or types of meas-
urement required for your needs during an on-going meas-
urement directly you should select the relevant nu-
clides/types of measurement in the small nuclide ta-
ble/measurement type table for the measurement menu.
Perform background measurement. The background is
subtracted for each measurement. The background should
match your ambient conditions and you should check and
update it occasionally (at least once a week). For dose rate
probes, there is a so-called intrinsic background, which is
determined under very special measuring conditions in the
factory (special and extensive shielding). This value must
not be changed.
To simplify handling, the device allows you to hide single or
all menus for the measurement operation. On the other
hand, the menus can be enabled only to View only the pa-
rameters or to View and change the parameters. The su-
pervisor of the unit should carefully consider which menu
mode is suitable for his area of work. A password is re-
quired to enable the menu.
Upon delivery, the password is 0.
