6.3.3 Programming of audio alarm threshold levels of gamma radiation DER and
switching on/off audio signaling of registered gamma quanta
The DER threshold level value of 0.30 μSv/h, which is the maximum permissible
level for premises in compliance with the regulatory documents of Ukraine, is set
automatically when the dosimeter is switched on.
Programming (change) of audio alarm threshold levels of DER is performed in
the mode of gamma radiation DER measurement, if necessary. To start
programming, press and hold the THRESHOLD button. The low-order digit should
start blinking on the digital LCD.
Successive short presses and releases of the THRESHOLD button set the
necessary value of the low-order digit. Press shortly the MODE button to program
the next digit, which will start blinking at that.
Other digits are programmed likewise.
