3 Restore Upload Restore upload has a similar function as Calibrate, but considers
a validity date, for example, of older calibration data and automat-
ically performs a decay compensation.
First, you have to save the original set of parameters in the HOST
or the HART
®
Communicator as off-line parameters. The off-line
parameters can then be restored to the detector. Then enable this
parameter set with Restore Upload. The validity date (Restore
Date) of the calibration, which is contained in the off-line parame-
ters, will automatically be compared with the current date in the
detector and the calibration count rate is adjusted accordingly.
4 Restore Date Restore Date contains the validity date that is used for the function
Restore Upload. It can be loaded with the calibration data set or
entered by hand.
2.26 Adjust Lower Point
Menu path: Device Config Setup Cal Parameter Adapt
Calibration Adjust Lower Point.
Use this function:
• after a source replacement to re-calibrate an existing multi-
point calibration (> 2 calibration points). All you need is one
calibration point at empty, or at least at a low level.
• if the characteristic curve has been entered in the detector
based on calculation records as a multi-point calibration. All you
need for calibration is one calibration point at empty, or at least
at a low level. If no full absorption is to be expected at 100%
level, we also recommend a calibration at 100% level, 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 Lower Level Level in % at which the lower calibration point is to be read in. With
empty container or at a level below the measuring range it would
be 0%. If 0% is not possible, the lower calibration point can also be
read in at a low level, for example, 20%.
