R.A03 - Set point 3

R.A03 - Set point 3
This parameter is available only when one of the logic inputs is
configured for SP3/SP4 selection.
Upper display: Gr.1
Lower display: SP3
Range: from "rL" [R.E10] to "rH" [R.E11].

R.A04 - Set point 4

R.A04 - Set point 4
This parameter is available only when one of the logic inputs is
configured for SP/SP2 selection and the other for SP3/SP4
selection.
Upper display: Gr.1
Lower display: SP4
Range: from "rL" [R.E10] to "rH" [R.E11].

R.A05 - Carbon monoxide factor setting

R.A05 - Carbon monoxide factor setting
Upper display: Gr.1
Lower display: COF
Range: from 1 to 1000

When a primary variable different from “O2” is selected.

NOTES:

NOTES:
1) COF is the keyboard selectable correction factor applied to

the Carbon algorithm.
It is used to bring carbon potential as calculated by the

instrument into alignment with actual carbon potential as
determined by shim stock analysis.
The default value of 200 corresponds to carbon potentials for
plain carbon steel in an atmosphere containing 20%
carbonmonoxide (CO). (See COF and H2F adjustment diagram
at pag. 56).

2) Changing the A.In.F [C.D07] parameter from "nonE" to "CO";

this parameter is forced to 200.

R.A06 - Hydrogen factor setting

R.A06 - Hydrogen factor setting
Upper display: Gr.1
Lower display: H2F
Range: from 1 to 1000.

When a primary variable different from “O2” is selected.

NOTE:

NOTE:
H2F is the keyboard selectable correction factor applied to the
dew point algorithm.
It is used to bring dew point as calculated by the instrument into
alignment with actual dew point as determined by a direct dew
point measuring instrument.
The default value of 400, corresponds to endothermic gas
containing 40% Hydrogen (H

(See COF and H2F adjustment diagram at pag. 56).
