- DER analogue scale (seven
segments) in a logarithmic gauge
Number of indicated segments (from left to
right) corresponds to the following DER
threshold values on the LCD display:
- one segment – 0.1 Sv/h;
- two segments – 1 Sv/h;
- three segments –- 10 Sv/h;
- four segments – 100 Sv/h;
- five segments – 1 mSv/h;
- six segments – 10 mSv/h;
- seven segments – 100 mSv/h
