Consider the arithmetic mean of five last measurements after the LCD stops blinking as
the DER measurement result. Every registered gamma quantum will be followed by an audio
signal. Measurement intervals and subranges will be set automatically, depending on the
measured radiation intensity.
Note. The statistical processing of data can be rerun forcibly to perform effective evaluation
of the radiation level. To do this, press the THRESHOLD button and hold it pressed during two
seconds. Rough evaluation of gamma background level can be performed within 10 s.
2.3.3.3 Programming of audio alarm threshold levels of photon-ionizing
radiation DER
Programming of audio alarm threshold levels of DER is performed in the mode of photon-
ionizing radiation DER measurement.
