- 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 µSv/h;
- two segments - ≥ 1 µSv/h;
- three segments - ≥ 10 µSv/h;
- four segments - ≥ 100 µSv/h;
- five segments - ≥ 1 mSv/h;
- six segments - ≥ 10 mSv/h;
- seven segments - ≥ 100 mSv/h.
