To measure surface beta-particles flux density, remove the filter cover
from the window, located opposite the detector, direct the dosimeter with
the window in parallel to the examined surface and place it as close as
possible.
In the mode of surface beta-particles flux density measurement the
dosimeter's LCD displays the following information (Figure 14):
- statistical error (1) of the measurement result (8);
- "β" symbol (2) – an indication of the measured radiation type;
- indicator of instantaneous value (3);
- sound symbol (4) (if audio signaling of registered gamma quanta and
beta-particles is switched on);
- alarm clock symbol (5) (if the alarm clock is on);
- alarm type symbol (6);
- battery status symbol (7);
- measurement result (8);
- dimension of measurement result (9);
- current time (10);
- threshold level of alarm actuation (11).
