Figure 5 – Mode of DER measurement and indication
This window displays the DER, the gamma radiation pulse
count rate, and the estimated limits of the expected relative
statistical deviations of the measurement result given the
confidence probability of 0.95 (Figure 5). The resolution of the
display of the gamma radiation pulse count rate is 1 cps. A unit
of measurement is specified next to each value, according to
which the data is currently displayed.
Note. If you need to recalibrate the device by the sigma
threshold, hold down the ENTER button for at least 2 seconds
in the DER measurement and indication mode.
WARNING! The effect of powerful electromagnetic
radiation on the device can cause false readings and false alarms.
