If this error is reached, a part of statistical information starts to be rejected while
the measurement process continues. Therefore, all following measurement results
will have the statistical error, which is equal to or less than the specified one.
The dosimeter can automatically determine the specified statistical error
depending on the radiation intensity (Appendix C). The user can also do that in the
submode of alarm threshold level programming. A blinking "%" symbol means that
the user determined the statistical error.
If the specified statistical error is determined automatically by the device, its
value is blinking on the LCD until it remains greater than the value of main relative
permissible error limit of surface beta-particles flux density measurement (Table
1.1). If the specified statistical error is determined by the user, its value is blinking on
the LCD until it remains greater than the value of the specified statistical error.
While the statistical error value keeps exceeding 99 %, the LCD displays the
"пп%" symbols.
Press the THRESHOLD button in the mode of surface beta-particles flux
density measurement to view the value of the specified statistical error. The value of
the specified statistical error is displayed on the LCD (Figure 15) while the
