9.6 Getting Started
The conditions at the facility affect the safety of the measuring sys-
tem. Therefore, the mounting and installation instructions in the
User’s Manual have to be observed.
In particular, the correct setting of the parameters via the HART
®
Communicator has to be ensured. For more information on the
parameters and on getting started, please refer to the User’s Man-
ual LB 490, ID no. 38477BAx.
Minimum setting for the safety function are the calibration and cur-
rent output parameters.
The information below refers to the operation with the HART
®
Communicator. If you are using another user interface to set up the
Uni-Probe parameters, e.g. Siemens SIMATIC PDM, please consult
the relevant chapter in the respective User’s Manual.
Prerequisite for the following sequence of operation is:
• that the shielding or the radiation source have not yet been
installed
• the Uni-Probe has been installed
• the Uni-Probe is supplied with power
• that communication with the Uni-Probe has been established
via an operating device, e.g. a HART
®
Communicator. Uni-
Probe
• that a two-point calibration is carried out. If another type of
calibration is selected, you have to carry it out in accordance
with the User’s Manual, parameter basic setting!!
See User’s Manual ID no. 38477BAx, Volume 3, chapter
"4.1 Preparing Calibration" and "4.2 Operation Modes for Cali-
bration".

Measuring the background
– See Volume 3, chapter "4.3.1 Measure Background" and
explanations in chapter "6.1 Background".
Install shielding with radiation source and then open the radia-
tion channel!
– See Volume 2, chapter "2 Installation".
Empty calibration
The level must be below the measuring range.
– Empty calibration has to be carried out as described in the
User’s Manual. See Volume 3, chapter "4.3.2 Empty Cali-
bration".
Full calibration
The level must be above the measuring range. If this is not
possible, you may also close the source shielding. If only the
