The window is divided into two independent display areas: the
upper one captures DER and the pulse count rate of gamma
radiation, while the lower one – DER and the pulse count rate of
neutrons. The resolution of display of the pulse count rate of gamma
radiation is 1 cps, that of neutrons – 0.01 cps. A unit of measurement
is specified near each value, according to which the data is displayed
at this point of time.
Also, each display area has an analogue scale of pulse count
intensity, which automatically changes the gradation depending on
the radiation intensity. A statistical error in percentage is displayed
as well (Fig. 5).
If the set threshold level of alarm triggering by sigma threshold is
exceeded, the
and
icons alternately appear in the
corresponding area. If the threshold level of alarm triggering by
neutrons count rate is surpassed, the
and
icons alternately
appear in the relevant area, whereas actuation of both alarms makes
and
alternately appear. Light, sound, and/or vibration alarm
also turns on according to the device’s settings.
On exceeding of the set threshold level of alarm triggering by the
safety level, the
icon appears, and light, sound, and/or vibration
alarm also turns on according to the device’s settings.
In exceeding the set threshold level of alarm triggering by
accumulated dose, the
icon appears, and light, sound, and/or
vibration alarm also turns on according to the device’s settings.
Note.
If you need to recalibrate the device by sigma-threshold for
gamma radiation, you need to hold down the central joystick button
for at least 2 seconds in the mode of DER measurement and
indication by gamma and neutron channels.
