2.3.6.2
Switching LCD backlight on/off
2.3.6.2.1 Press shortly LIGHT to switch the display backlight on for 8 s. The
backlight switches off automatically in 8 s.
2.3.6.2.2 To switch on continuous backlight of the dosimeter LCD, press and
hold LIGHT (circa 6 s) until the backlight shortly blinks for two times.
2.3.6.2.3 Press shortly LIGHT to switch off the back-lit LCD.
2.3.6.3
Managing registered gamma quanta, alpha and beta particles
signaling
2.3.6.3.1 Signaling of registered gamma quanta, alpha, beta particles
(depending on the type of the connected probe) is done only in the mode of
measurement results display obtained from the probes or detectors. One can manage
signaling only in this mode.
2.3.6.3.2 Shortly press SOUND to switch on signaling of registered gamma
quanta, alpha, beta particles. A short audio signal will follow every detected gamma
quantum, alpha or beta particle.
2.3.6.3.3 Press shortly SOUND to switch signaling off.
2.3.6.3.4 Press shortly SOUND one more time to switch signaling on again.
2.3.6.3.5 Signaling status is displayed on the dosimeter LCD with
symbol .
2.3.6.3.6 Signaling of registered gamma quanta, alpha or beta particles can be
applied to searching for ionizing radiation sources. When approaching a source of
ionizing radiation the amount of gamma quanta, alpha or beta particles will increase
and the number of short beeps increases correspondingly. On approaching towards
the source, intermittent beeps will merge into a continuous audio signal – it will
become impossible to continue searching.
To continue searching, press and hold SOUND for 4 s. Not all registered
gamma quanta, alpha or beta particles will be followed by signaling upon that, but
each
n
th
.
The n number (divider of signaling) is generated in such a way that given the
current ionizing radiation intensity, intermittent beeps are generated about once per
second. This will make it possible to continue approaching towards the source of
ionizing radiation.
If ionizing radiation intensity changes, the divider of signaling may be
recalculated as many times as necessary. To bring the divider of signaling back to
the initial state (
n =1, each gamma quantum, alpha or beta particle is accompanied by
a short signal), turn signaling on and off by shortly pressing SOUND.
