"Density value" (*1C)
This function is used to enter the density of the calibration point. The value must be determined
from the sample in a laboratory measurement.
!
Note!
When entering the value, temperature influences have to be taken into account. The density
entered must refer to the temperature at which the pulse rate has been determined. If the density
and the pulse rate have been determined at different temperatures, the density value must be
corrected accordingly.
"Calibration point" (*1D)
This function is used to specify, if the current calibration point is to be used
Options:
• not used
The calibration point is not used. However, it can be reactivated at a later point in time.
• used
The calibration point is used.
• clear
The calibration point is deleted. It cannot be reactivated at a later point in time.
"Absorption coefficient" (*1E)
This function displays the absorption coefficient which results from the currently active calibration
points. The displayed value should be used for plausibility checking.
!
Note!
If only one calibration point is currently active, the absorption coefficient is not calculated. The last
valid value is used instead. At the first commissioning or after a reset, the default value,
μ =7.70mm
2
/g, is used. The value can be changed by the user.
