If the transmitter is set up to have readout or output of combustibles, oxygen deficiency, maximum carbon
dioxide or combustion efficiency, then the fuel constituents must be entered. Any or all of the variables can
be modified and entered in COMMISSIONING menu functions #50 to 56. (See chapter 7.2.23). Your fuel
supplier or chemist should be able to give you all these values.
A
is the heat of combustion of the fuel per gram atom of contained carbon.
H
is the H/C atom ratio in the fuel.
O
is the O/C atom ratio in the fuel.
N
is the N/C atom ratio in the fuel.
S
is the S/C atom ratio in the fuel.
M
is the ratio of H
