2.3.6.5.3 Submode of the control unit "Viewing and programming of new
values of the alarm threshold level and the specified limits of statistical deviations
(specified limits of the expected relative statistical deviations of the measurement
result at 0.95 confidence probability)" during DER measurement
2.3.6.5.3.1 Press THRESHOLD to view current values of the alarm threshold
level and the specified limits of statistical deviations. In this case, the control unit
should be in the mode of "Measurement results display obtained from the probes or
detectors".
The LCD will show the following information (Figure 2.12):
- symbol of the measured radiation (1);
- alarm threshold level (2);
- threshold level dimension (3);
- specified limits of statistical deviations (4);
- THRESHOLD transparency (5), reflecting the alarm threshold level;
- battery status symbol (6);
- navigation receiver status symbol (7);
This information is displayed on the LCD while THRESHOLD is held down
(but not longer than 4 sec).
(viewing the alarm threshold level and specified limits of statistical deviations)
2.3.6.5.3.2 If you keep holding THRESHOLD for more than 4 s, the value of
the alarm threshold level is returned to zero, and its low-order digit starts blinking
(Figure 2.13). Then release THRESHOLD.
