Methods for entering the calibration points
Automatic calibration
For an automatic calibration, the vessel is filled to the required value. For the background calibration
the radiation remains switched off, for the other calibration points the radiation is switched on.
The Gammapilot M automatically records the pulse rate. The associated level is entered by the user.
Manual calibration
If during the commissioning of the Gammapilot M one or more calibration points can not be realised
(e.g. because the vessel can not be sufficiently filled or emptied), the calibration point must be
entered manually.
That is, not only the level but also the associated pulse rate must be entered by the user. For details
concerning the calculation of the countrate please refer to your Endress+Hauser sales organisation.
Note!
When calibrating manually, the calibration date is not set automatically. Instead, it must be entered
manually into the "calibration date" (*C7) function.
Note!
A manually entered calibration point should be replaced by an automatic calibration as soon as the
associated level occurs during the operation of the plant. This recalibration is advisable, because
automatic calibration points result in more precise measuremtns than calculated ones.
