5.8 Defining the Upper/Lower Pulse Rate
Limit
This function is enabled only for special applications. Enter a value
unequal to zero to enable the upper threshold. If the current count
rate exceeds the upper threshold, the measurement is halted until
the count rate has dropped below the upper threshold again. If the
current count rate falls below the lower threshold, the measure-
ment is also halted until the lower count rate threshold is exceeded
again.
If the measurement has been stopped, the measured value display
and output are held. The count rate where switching takes place is
the current non-averaged count rate.

Entering 0 disables the function.
Go to the function block
TRANSDUCER.
Enter the values for the pulse rate threshold in the parameters
LE_MAX_SENSOR_VALUE and LE_MIN_SENSOR_VALUE.
Send the entries to the Uni-Probe.
This completes the setting.
