(submode of the alarm threshold level and specified limits of statistical
Programming of the alarm threshold level and specified limits of statistical
deviations when alpha radiation characteristics are measured is similar to
programming of the alarm threshold level and specified limits of statistical deviations
in the event of photon-ionizing radiation DER measurement (2.3.6.5.3.2 of this OM).
Important! Programming a zero threshold level, switches off this threshold
alarm.
Programming a zero value of the specified limits of statistical deviations turns
on automatic determination of the specified limits of statistical deviations by the
dosimeter depending on the radiation intensity.
Important! If the submode of the alarm threshold level and the specified limits
of statistical deviations programming is paused for more than 20 seconds (the user
will not click any button), the control unit automatically returns to the mode of
measurement results display obtained from the probes or detectors. All changes that
have been made in the submode of new values programming will be canceled.
2.3.6.8 Measurement of accumulated photon-ionizing radiation DE and
DE accumulation time
2.3.6.8.1 General information
2.3.6.8.1.1 Accumulated photon-ionizing radiation DE is measured with the help
of the detector built in the control unit.
2.3.6.8.1.2 Measurement of accumulated DE and DE accumulation time begins
when the control unit is switched on, after its display and alarm tools testing finishes.
Accumulated DE and DE accumulation time are measured during the entire period of the
control unit operation and do not depend on its operating modes.
2.3.6.8.1.3 DE accumulation history is saved in the nonvolatile memory of
the dosimeter simultaneously with measurement of accumulated DE and DE
accumulation time (2.3.4 of this OM). The nonvolatile memory capacity provides for
saving up to 2200 DE values. The saving interval depends on DER and falls within
10 to 1 minute. DE is also saved when you turn the dosimeter on and off.
