8.1.1

Oxygen Analyzer_Current Output Setting

This section describes setting of the analog output range. Table 8.1 shows parameter codes for
the set items.

*1: For the oxygen analyzer, set 0 (zero) only for parameter code C01. When it is set, the current output is 4-mA fixed regardless of
the oxygen concentration.
8.1.2

Oxygen Analyzer_Analog Output Setting

This section describes how to set the analog output range.
(1) To provide an oxygen concentration, use parameter code C11 to set the minimum
oxygen concentration at 4 mA, and use parameter code C12 to set the maximum oxygen

concentration at 20 mA.

(2) To provide a humidity output, use parameter code C13 to set the minimum humidity at 4 mA,
and use parameter code C14 to set the maximum humidity at 20 mA.
(3) To provide a mix ratio, use parameter code C15 to set the minimum mix ratio at 4 mA, and
use parameter code C14 to set the maximum mixing ratio at 20 mA.
Refer to Table 8.2 for the parameter codes.
