Using the Dosimeter Setting Device and a PC, you can write PC-edited values to / read
measurement data trend from the Dosimeter NRF31 via communication with the device.
If worn tight to the body, energy characteristic of the NRF31 series enables direct reading of dose
equivalent at the depth of 1cm (unit: Sv or rem, 1Sv is equivalent to 100 rem).
You can switch Sv and rem units through the Dosimeter Setting Device. Default setting of
NRF31021-
