has to select the Exit parameter at the end of the parameter settings list and press the
ENTER/SAVE button.
8. There are some parameters/information the user cannot change e.g. unit serial
number, calibration coefficients, etc.
The following is a list of settings, their values, and defaults (for Screen 3). The defaults are
highlighted by green.
Dose Unit: user can select Sv/hr or Rem/hr.
Acquisition: user can set acquisition time for spectrum and dose rate profile.
Spectrum Accumulation Time: Conti (continuous), 10s, 30s, 60s, 100s, 300s, 1000s, 1hr, 2hr
The dose record time can be set from 10 seconds to 24 hours according to the following
parameters: 10s, 30s, 60s, 100s, 300s, 1000s, 1 hr, 2 hr, 8 hr, 12 hr, 24 hr.
