4.8.6 Average Function
Not used in USA.
The each active sensor point the Gas Controller calculates the arithmetic average value out of 10
measurements got within the time unit defined in the menu „AV-time“. Depending on the definition of the operating
mode the alarm is evaluated with the current or the average value. In the average mode, the average value is
indicated in the menu “Sensor Values” next to the current value. The control mode (current or average value) for the
evaluation of the alarm is defined for each sensor point.
The alarm evaluation of the control mode “Average Value” is overlaid by the current value, when the current value
exceeds the alarm threshold defined in the menu “AV-Overlay”. The overlay is delayed by the time factor defined in this
menu. The average overlay function is only active for the gas type CO.
