4.2.15 CALIBRATION  ADJUST UP. CAL. PT
Set the upper calibration point.
 Define the level for the upper calibration point and confirm the
input with OK.
IMPORTANT
Typically, the upper calibration point is at 100% level. In case of a
multi-point calibration, the adjustment will adjust all other calibra-
tion points proportionally.
The calibration sequence is described in detail in Volume 3, sec-
tion 4.
4.2.16 CALIBRATION  CHECK CURVE
This function allows you to check the calibration curve for errors
and to sort it. This function is particularly helpful for multi-point
calibrations.
The following will be checked and carried out:
• Monotony: rising level – falling count rate
• Full pulse rate greater than background pulse rate?
• Sort calibration points by count rate
IMPORTANT
Always select this function at the end of the calibration process to
ensure that your calibration data is plausible.
The calibration sequence is described in detail in Volume 3, section
4.
