The main dosimeter function is to measure pulsed radiation with a pulse duration from 10 ns (AT1123), short-term radiation with a pulse duration from 30 ms and continuous x-ray and gamma radiation in wide ranges of ambient dose equivalent rate and energy. The instruments detect soft and hard gamma radiation sources, beta radiation sources, short-term and pulsed radiation with exposure time assessment, and detect moving irradiators as well. Use the instrument keyboard to setup any thresholds from the whole measuring range. The instruments save automatically the maximum dose rate value. They keep for long time 100 measurements results in the nonvolatile memory and they are able to transfer data to PC with the rate from 300 to 19200 baud.
The instruments have the self-testing mode which starts at switching-on and continues within dosimeter operation. There is no need to use a reference source because of LED stabilization of the measuring path.
