User manual

The device analyzes a diversion of current value regarding
a result of the previous observation and averages it. If the
difference exceeds a defined value, the current result is
displayed instead of the average one. For example, as results
of three observations the average result is 0,20 µSv/h, and the
current value 0,80 µSv/h is registered in the fourth cycle, than
the result of the fourth observation will not be averaged and we
shall see 0,80 µSv/h and the icon « ». This function of the
article allows detecting sharp changes of dose rate.
If you want to find a source of radiation turn off a threshold,
switch on audio signal and pay attention not to digital readouts
only but a sound frequency and frequency of appearances of
the icon « » . Its appearance frequency is proportional to
a dose rate thus the higher the frequency the closer you are to
a source.
