As soon as the measurement is started the surface beta-particles flux
density measurement results (8) and the statistical error values (1) that
correspond to these results begin to be formed on the LCD.
If the flux density measurement results exceed the alarm threshold level
(11), the dosimeter sends a two-tone audio signal and/or an intermittent
vibration signal, which depends on the chosen alarm type. Measurement
results start blinking on the LCD of the dosimeter. Periodic and gradual (from
left to right) highlighting of the sound symbol segments (4) serves as an
indication of the threshold level exceeding as well.
The ten-segment indicator of instantaneous value (3) is used for fast
evaluation of intensity of photon-ionizing radiation and beta-particles flux.
The integration time during measurement of the instantaneous intensity
value and the time of information update on the instantaneous value
indicator are equal to 500 ms.
The instantaneous intensity value is displayed in pseudo-logarithmic
scale. The first segment of the indicator becomes highlighted when the
intensity corresponds to 2 pulse/s pulse rate from the Geiger-Muller
counter.
