2.5 The dosimeter sends a one-tone audio signal if gamma quantum or beta-
particle gets to the detector, and a two-tone audio signal if the programmed DER, DE
or surface beta-particles flux density threshold levels have been exceeded.
2.6 Low battery status is indicated by the dosimeter.
2.7 DER, DE and surface beta-particles flux density values as well as DER, DE
and surface beta-particles flux density threshold level values appear on the digital
LCD indicating the correspondence of information. The values of DER and DER
threshold level are expressed in µSv/h, the values of surface beta-particles flux
density and surface beta-particles flux density threshold level are expressed in
3 2
10 part./(cm ·min), and the values of DE and DE threshold level are expressed in
mSv.
