Calibration Adjust Upper Point.
Use this function if no full absorption is expected at 100% level and
the curve has already been entered in the detector based on calcu-
lation records as multi-point calibration.
In this case, you can carry out, after a previously done empty
adjustment with Adjust Lower Point, an additional calibration
with full container, with Adjust Upper Point.
The calibration has the effect that all other calibration points are
adjusted accordingly in percent.
1 ReadIn Start reading-in the count rates. While the count rate is read in, the
average is calculated and displayed continuously. The reading-in
period is defined under ReadIn Time, which is located in the Cal
Settings menu.
2 Upper Level Level in % at which the upper calibration point is to be read in. With
full container or at a level above the measuring range it would be
100%. If 100% is not possible, the lower calibration point can also
be read in at a lower level, for example, 80%.
3 Upper Rate Level in % at which the upper calibration point is to be read in. With
full container or at a level above the measuring range it would be
100%. If 100% is not possible, the lower calibration point can also
be read in at a lower level, for example, 80%.
Select ReadIn to read in the count rate.
If you already know the value, you can enter it here.
Preferably, the upper calibration point should be recorded at 100%
level or with a full container. Other levels for calibration are possi-
ble, but can then calculate the 100% value only, which may lead to
deviations in the display with an actually full container.
4 Upper Comp Rate Available only if Compensation Mode = AUTO PRC or AUTO
GPC is selected.
Contains the count rate of the compensation measurement for the
upper 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 Upper 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 UP Calculates a new calibration curve based on the value pair (Upper
Level + Upper Rate) and the calibration curve which is stored
under Cal Points. The new curve is also stored under Cal Points.
