For pulse probes there are six pulse rate ranges that will also be selected automatically:

When exceeding the highest range, the flashing full scale value (»9...9«) will indicate overrange.
Remark on the probe 6150AD-0: this is a general purpose probe type, the pulse rate of which is indicated
directly without applying any calibration factor. We created this probe type for future developments of
pulse probes that will connect to any 6150AD model. Because one cannot foresee the range of a future
pulse probe, the 6150AD-0 range goes up to 999 kS
-1
, that is approx. 1 MHz, which is about the
maximum count capacity of the 6150AD. That high range is a reserve for the future not required by any
of the probes currently available.

The range is the same for all detectors (internal tubes and probes). However, the Scintillator Probe
6150AD-b cannot use the full range because its dose rate range ends at 99.9 µSv/h. You may observe
mean values greater than 99.9 µSv/h with the 6150AD-b, but such mean values are not reliable because
they are out of range.
When exceeding the highest range, the flashing full scale value (»9...9«) will indicate overrange.
