The AVF is built under the circuit of standby multi-
vibrator with transformer multiplying of voltage, and
serves to form the anode voltage + 400V, required to
operate the detector.
The DCC is implemented on the basis of a number
of switching and regulating elements, and serves to
regulate the "dead time" of the detector.
The NVM is implemented on the basis of EEPROM
and serves to record the history of time and dosage.
A piezoacoustic converter is used as the LS.
