Monitor

On startup, the device operates in this mode. All incoming data is accumulated and analysed. When a change in the radiation environment is detected, the device starts a new accumulation interval. When no changes are detected, it continues averaging to increase the confidence of the estimate.

Displayed values are considered valid if:

their random error does not exceed 30% for the dose rate and 50% for the count rate
the device sensor temperature is below +45 °C

Low-confidence values are shown with digits hatched with light diagonal stripes.
Valid values are shown with fully filled digits.

Two operating ranges:

Pulse mode (1): from 0.1 µSv/h to 1 mSv/h. Data comes from the scintillator by registering individual flashes, which allows estimating low radiation levels and searching for sources. Energy response compensation uses a predefined calibration function programmed at the factory. Clicks and count rate are available — the device clicks on each registered photon and shows cps values.

Current mode (2): 1 mSv/h to 9 Sv/h. A different mechanism is used for real-time dose rate estimation based on an integral value. Clicks and detector count rate remain available, but the click tone is different in this mode. This mode is required for operation in high radiation fields.
