8. Detailed Data Setting
8.1 Current Output Setting
This section describes setting of the analog output range.
8.1.1 Oxygen Analyzer - Setting Minimum Current (4 mA)
and Maximum Current (20 mA)
To set the minimum and maximum currents, proceed as follows:
(1) Select [Commissioning] in the Execution/Setup display.
(2) Select the “mA-output setup” in the Commissioning display.
(3) Select “mA-output1” in the mA-outputs 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 vol%O
2
.
(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.
8.1.2 Humidity Analyzer - Setting Minimum Current (4 mA)
and Maximum Current (20 mA)
To set the minimum humidity to 50% H2O and the maximum humidity to 100% H2O,
follow these steps:
(1) Select Setup in the Execution/Setup display.
(2) Select the mA-output setup in the “Commissioning” (Setup) display.
(3) Select mA-output1 in the mA-outputs display.
(4) Select the Max. humidity conc. in the mA-output1 range display and press the [Enter] key.
The numeric-data entry display then appears. Enter the humidity value for the maximum
current (20 mA); for example, enter “100” for 100% H
2
O.
NOTE
For the humidity measurement, 0% H
2
O is a default setting for the minimum humidity and 25%
H
2
O is the default for the maximum humidity. If you first attempt to set 50% H
2
O for the minimum
humidity, you cannot set it because that value is outside the set range. In such a case, set the
maximum humidity first.
(5) Select the Min. humidity conc. and enter a minimum humidity value, e.g., 050 for 50% H
2
O.
(6) Follow the above steps to set the mA-output2, if necessary.
8.1.3 Input Ranges
The range low and high values are restricted as follows:
