2.3.3.8 Energy calibration
Calibration of the device by the energy allows using a calibration
sample containing
device's detector. It is performed every 6 months maximum. It is
available only when the device is switched on in the
"Administrator" mode.
IMPORTANT! To perform calibration, it is necessary that the
device remained in regular steady-state condition for at least 2 hours
prior to calibration and the conditions must be unchanged in its
process. One also needs to make sure in the absence of other sources
of photon-ionizing radiation affecting the calibration result.
