6.1.8 SettingOutputSmoothing“SMoo”
Iftheoxygenconcentrationofsamplegasrapidlychanges,andthemeasuredvalueisusedfor
control, harmful results may occur such as frequent on and off switching.
In such a case, signal changes can be smoothed by giving an appropriate time constant and
performing calculation. Smoothing factor from 0 to 60 seconds can be set. When the output smoothing
is set, the smoothed value is an instantaneous value, which is displayed and output in analog form.
The smoothed value is also used as the instantaneous value for checking the concentration alarm and
for RS232 communication. The output smoothing is “non“ 0 second by default.
