Monitoring mode
This mode gives a value of a dose rate displaying
indications on the LCD. Every registered quantum is displayed
on LCD as « » icon. Blinking frequency of « » icon is
proportional to the strength of a radiation dose rate.
A short cycle of observation is introduced in order to reduce
a waiting time of the first reading. The indications of a short
cycle and its icon of two parallel lines « » (page 10,
paragraph 4) are displayed within 10 s, but have a rough value
and are updated during the next three subsequent short
cycles. The readings of a short cycle are effective as initial
estimation of a radiation dose rate
Within 40 s after activation the device gives the first
indication which is presented on display as side of a square
« » and shows a number of performed observations.
These icons (page 10, paragraph 4) allow determining
visually the number of averaging cycles. They are extremely
useful for detection of a strong variation in a radiation dose
rate (for example in case of a local/domestic radioactive
contamination) as in such circumstances the icon « » will
be changed to « » and that it is quite easy to note. At the
same time the estimation of a dose rate starts all over again
from the first cycle, so averaging indication of the previous
cycles are not taking into account.
