Note!
Correct selection of the switching threshold is important for a reli-
able function of the limit value switch. To avoid false alarms if the
switching threshold has been set using a fixed value, the time con-
stant has to be set to automatic, or it has to be calculated accu-
rately.
Perform a calibration in code 36 to check if your setting is correct.

>0 Fixed value in % C
If the switching threshold is exceeded, the device indicates an
alarm.
If the switching threshold is set to automatic (factory setting), it is
already set up optimally. If you wish to set another switching
threshold, you can enter a fixed value in cps.
You can enter the switching threshold either as a percentage value
in this code or in code 18. Every entry in this code automatically
calculates the new count rate in code 18. Vice versa: If you enter a
fixed value (count rate) in code 18, then the percentage value in
code 17 is calculated new.
The calibration of bulk cone measurements switching at a certain
bulk cone diameter is described on page 62.
