IMPORTANT
The use of the function "Rapid Switch" is recommended only for special appli-
cations where the output signal has to adapt rapidly to the new value, e.g. in
case of measurements on small tanks and if sudden level changes occur.
When Rapid Switch (Fig. 108, item 1) is activated, there is a rapid reaction (Fig. 108,
item 2) to a quick change in level. The time constant in this case is set to 1/10. After
that, the time constant is reset to the original value. A change in level is considered
to be a "rapid" change when the count rate is changing more than the entered
sigma value within a short time. The sigma value can be adjusted to the process. A
sigma of 4.0 is factory set at delivery.
