When using the dosimeter in a temperature range from -40 up to -20 C the
Dosimeter provides performance of the dosimetric functions without displaying the result of
measurement on LCD. When returning the dosimeter into conditions with a temperature
higher than -20
С LCD operates in a normal way.
The dosimeter performs continuous DER and DE measurement, DE accumulation
time counting in all modes, excluding an active mode of data transmission to PC (Ir/on).
Standard configuration of the dosimeter when shipping ensures indication of the
following parameters and functions performed:
DER measurement mode
– On
On a display (2), figure 1.2

2.4.2 Selection of an indicated parameter
Modes of DER, DE, dosimeter’s number and data transmission to PC indication are
switched on by a successive pressing of the MODE button (figure 2.1 and 2.2).
The dosimeter allows switching on/off all the above-mentioned indication or
measurement modes. Change of the configuration is performed in the mode of data
transmission to PC.
2.4.3 DER measurement mode
In the DER mode (figure 2.1 and 2.2) the following values are indicated on the LCD:
- DER ( Sv/h, mSv/h, Sv/h);
- DER on the analogue scale in a logarithmic gauge (seven segments);
- statistical error in percents;
- averaging time of DER values (Range of the averaging time indication is from 1 up
to 2999 s. If the averaging time exceeds 2999 s, the symbols “
- - -
” are indicated on the
LCD).
