Remarks:
1. With the 6150AD1/2, the threshold 7.5 (µSv/h or S
-1
) takes the value 7 (µSv/h or S
-1
), because the
6150AD1/2 can only store integer dose rate thresholds. Apart from that, all 6150AD models provide
the same sets of thresholds; only the format (number of digits after the decimal point) may vary, see
section 6.3.
2. The option »OFF« (warning disabled) appears differently according to the model: when indicating
the dose rate alarm threshold, the 6150AD1/2 leaves the digital display blank, whereas the
6150AD3/4/5/6 displays »OFF«.
3. » « marks the default threshold that is active after switching on or after connecting a probe.
