Using buttons
The following quick control options are available in this mode by using the buttons:
· short press on the swing button "up" switches between the display types of photon radiation intensity -
dose rate or count rate;
· long press on the swing button "up" global turns on and off the sound signaling.
Setting alarm thresholds
Using the menu, you can set two alarm thresholds for the dose rate level. If the level of the alarm
threshold is exceeded, a pulsating sign will be displayed in the status bar:
- for Alarm 1;
- for Alarm 2.
On the rate of reaction to changes in the radiation environment
The lower the count rate, the longer it takes to obtain a reliable assessment of the dose rate. The smaller
the change in the radiation environment, the longer it will take to reliably detect that change. The higher
the sensor's sensitivity, the higher the counting rate. All other things being equal, the higher the counting
rate, the faster reliable assessment will be obtained.
The table below shows a comparison of radiation sensors for the required time to obtain reliable
assessment:

3.7.2 Dose
Dose mode is designed to represent the accumulated dose for X-ray and gamma radiation.
In the Dose display mode, the screen represents:
· status bar - at the top;
· vertical graphic scale of the accumulated dose - at the left;
· numerical value of the accumulated dose with its units - at the center and
on the right.
There is a standard information of Display modes on the right side of status bar.
The following information is shown on the left side of status bar:
Time of the dose accumulation: days, hours, minutes.
