About Input Ranges
IM 11M12A01-02E
This section describes setting of the analog output range.
To set the minimum and maximum currents, proceed as follows:
(1) Select Setup in the Execution/Setup display.
(2) Select the mA-output setup in the Setup display.
(3) Select mA-output1 in the mA-output display.
(4) Select Min. oxygen conc. in the mA-output1 range display and press the [Enter] key.
The numeric-data entry display then appears. Enter the oxygen concentration for the
minimum current (4 mA); for example, enter "010" for 10% O
(5) Select Max. oxygen conc. in the mA-output1 range display and enter the oxygen
concentration for the maximum current (20 mA) in the same manner as in step 4
above.
(6) Set mA-output2 in the same way as the setting procedure for mA-output1 given
above.
The minimum concentration of oxygen for the minimum current (4 mA) is 0% O
to 76% O
. The maximum concentration of oxygen for the maximum current (20 mA)
2
ranges from 5% to 100% O
set for the minimum. If it does not fall within this input range setting, the setting will be
invalid, and the previous set values will remain.
Setting example 1
If the setting (for a 4 mA current) is 10% O
the maximum (20 mA) point at 13% O
, and must be at least 1.3 times the concentration of oxygen
2
, you must set the oxygen concentration for
2
or greater.
