Keeping the updated calibration values for scintillator-based detectors is a challenge for the detectors of cosmic rays, as the detectors are normally installed outdoors in the field, away from the controlled climate conditions of the lab. Changes in temperature and weather in general, and other external factors can influence the detector performance and need to be monitored and calibration values updated. This publication describes the procedure of monitoring the calibration settings from the Horizon-T detectors in the conditions of high altitude and for the case of the long data-carrying cables from each detector when access to each detector may not be possible or very difficult at certain times.
