6.4.3 Oxygen Display Units
Options: Oxygen % / Oxygen ppm (parts per million).
Default:
Oxygen %.
The top line of the display that shows the oxygen measurement can be displayed in either % or ppm (see
chapter 5.2 Oxygen Display Units)
6.4.4 Damping Factor
Options: No Damping
1 – 10 Samples Averaged
Default:
5 Samples
The Oxygen measurement can be damped by averaging successive readings from the probe. This can be
used to smooth out minor fluctuations in the process gas level and should improve the stability of the
readings of the system. The larger the number selected here, the more successive readings are averaged
and the smoother the measurement will be.
The damping factor is not applied to the Probe EMF and Probe Temperature values used to calculate
oxygen, but to the oxygen value itself. The pre-damped oxygen value is not displayed or retransmitted via
digital or analog outputs, when damping is enabled the damped oxygen value is shown on the local display
as well as being retransmitted via digital or analog outputs.
6.4.5 Process Alarms
Options: Enabled / Disabled
Default:
Disabled
This function allows the operator to enable and disable process alarms. The process alarm menu functions
will also be hidden if the process alarms are disabled. (See also chapter 7.2.20 Process Alarms)
