The first settings page of the "measurement settings" is displayed for all operating modes.
The following configuration options are available:
• General settings
• Configuration of the reference time
• Selection of the isotope used (depends on the operating mode)
• Selection of the beam type (depends on the operating mode)
General settings
In the "slave mode" operating mode, no settings are made apart from the setting for
the operating mode.
The pulse rate, measured value and current shown on the optional display are also
filtered with the configured "Damping output".
1. Selection of the calibration or linearization type
 Depends on the operating mode
2. Configuration of the engineering unit for the level
 Depends on the "Level" operating mode with customer linearization
3. Configuration of the unit of length
 Depends on the operating mode
4. Configuration of the density unit
 Depends on the operating mode
5. Configuration of the calibration time
 The calibration time is the time to be measured for the calibration of the
individual calibration points. This time should be changed depending on the
measuring task.
6. Configuration of the output damping
 The output damping defines the time constant T
63
. The setting depends on the
process conditions. Increasing the damping value makes the measured value
considerably steadier but also slower. In order to reduce the influence of stirrers
or turbulent surfaces, it is advisable to increase the damping value. However, the
value selected for damping should not be too large so that rapid changes in the
measured value can also be detected quickly.
Sample settings for the time constant T
63
:
Level: 6 s
Density: 60 s
