On startup, the device operates in this mode. All incoming data is accumulated and analyzed. 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 improve estimate reliability.

Grid Item
  • When data is insufficient, the digits are hatched with light diagonal stripes.
  • When the estimate is reliable, the digits are fully filled in.

Two operating ranges:

Pulse mode (1): 0.1 µSv/h to 1 mSv/h. Data comes from the scintillator in individual flash detection mode, enabling estimation of low radiation levels and source searching. Energy sensitivity compensation uses a pre-programmed factory calibration function. Clicks and count rate are available — the device produces audible clicks on photon detection and displays CPS values.

Grid Item

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.

  • Current time: hours, minutes
  • Detector temperature
  • Threshold exceedance indicator for dose rate, dose, and count rate
  • Sound indication status
  • Bluetooth or USB connection status
  • Rocker button lock indicator
  • Battery status

Lower area: dose rate or count rate value, graphical indicator, range number (1/2), units (Sv/h, rem/h or CPS/CPM), current display mode icon (Monitor).

Units can be selected via the menu: Sv/h or rem/h for dose rate display; CPS or CPM for count rate display.

The radiation intensity type (dose rate or count rate) can be selected via the menu or switched quickly using the device buttons.

Hotkeys:

  • Short ▲ — toggle dose rate ↔ count rate (pulse mode only)
  • Long ▲ — toggle sound indication on/off
  • Short ▼ — toggle photon clicks on/off (pulse mode only)

When alarm thresholds are exceeded — pulsing icons appear:

Dose rate:

“Alarm 1” — icon ; “Alarm 2” — icon ; “Out of scale” — icon

Count rate:

“Alarm 1” — icon ; “Alarm 2” — icon ; “Out of scale” — icon
