3 Lower Rate
Count rate with empty container or 0% level. If 0% is not possible,
the lower calibration point can also be read in at a low level, for
example, 20%.

Select ReadIn to read in the count rate.
If you already know the value, you can enter it here.
Tip
Preferably, the lower calibration point should be recorded at 0%
level or with an empty container. Other levels for calibration are
possible, but can then calculate the 0% value only, which may lead
to deviations in the display with an actually empty container.
4 Lower Comp Rate
 Available only if Compensation Mode = AUTO PRC or AUTO
GPC is selected.
Contains the count rate of the compensation measurement for the
lower calibration point. With
ReadIn the compensation count rate
is read in at the same time as the count rate for the level measure-
ment.
5 Lower Rate at Op
 Available only if Compensation Mode is not set to OFF .
Shows the count rate calculated under operating conditions,
depending on the respective compensation mode.
6 Adjust Curve LP
Calculates a new calibration curve based on the value pair ( Lower
Level + Lower Rate ) and the calibration curve which is stored
under Cal Points . The new curve is also stored under Cal Points .
