- DE and DER accumulation history;
- the preset DER and DE thresholds.
When using the instrument in a temperature range from -40°С up to –20 С the device
provides performance of the dosimetric functions without displaying the result of
measurement on LCD. When the instrument is returned to a temperature higher than –20 °С
LCD operates in a normal way.
The instrument performs continuous DER and DE measurement, DE accumulation
time counting in all modes, excluding an active mode of data transmission to PC (on/Ir).
Standard configuration of the instrument as includes the following parameters and
functions:
DER Indication Mode - On

2.4.2 Selection of an indicated parameter
DER, DE, instrument’s number and data transmission to PC modes are switched on by a
successive pressing of the MODE button (Figure 2.1, Item 6).
The dosimeter allows for switching all the above-mentioned indication modes on and off.
Change of the configuration is performed in data transmission to PC mode.
