1: For log oxygen scale details, Refer to Appendix 3.
2:
Note that the reducing oxygen span is shown on the display as the exponent only. -1
represents 10
-1 % oxygen.
3:
The oxygen deficiency output can be used in the same way as a combustibles
analyser to signal the extent of reducing conditions. As an example, if the oxygen
deficiency is 3 %, then the burner would need 3 % oxygen to bring it back to
stoichiometry.
4.
Always check that the “*” is on the RH end of the lower line to lock in the selection
before leaving the function.
5.
If output channel is selected for oxygen, and the temperature of sensor 1 or sensor 2
is below 650
°C (the display will be flashing “NOT READY”) the 4-20mA output for
the associated channel will be set to zero mA.
See set-up 91 for further details.
