Consider the arithmetic mean of five measurements after the LCD stops blinking
as a result of the surface beta-particles flux density measurement. Every registered
beta-particle and gamma-quantum will be followed by an audio signal.
Measurement intervals will be set automatically, depending on the measured
radiation intensity.
6.3.7 Programming of audio alarm threshold level of surface beta-particles
flux density
Programming of audio alarm threshold level of surface beta-particles flux density is
performed in the mode of surface beta-particles flux density measurement and indication.
To start programming, press the THRESHOLD button and hold it pressed (circa
six seconds) until the low-order digit starts blinking on the LCD. Set the appropriate
value of the low-order digit by successive pressing and releasing the THRESHOLD
button. Press shortly the MODE button to program the next digit, which will start
blinking at that. Other digits are programmed likewise.
