7.8.2 Humidity Analyzer - Analog Output Setting
Select any one of the analog output settings — Oxygen, Humidity, and Mixing from the mA-
output range display. If the /HS option is specified at the time of purchase, the equipment is a
humidity analyzer. For other than this setting, the analyzer is an oxygen analyzer. If a mixed
measurement is required, change the current output setting as given below. If the humidity
analyzer is specified in the above detector type setting, the analog output is set to “humidity”
when the data initialization is attempted.
(1) Select the Setup from the Execution/Setup display.
(2) From the Commissioning (Setup) display, select “mA-output setup”; the display shown in
Figure 7.9 then appears.
(3) Select “mA-output1” from the “mA-outputs” display. The “mA-output1 range” display shown
in Figure 7.10 then appears.
(4) Select the Parameter, then the Oxygen, Humidity, and Mixing appear in the mAoutput1
range display (Figure 7.11). Select “Mixing” and press the [Enter] key.
(5) The “Mixing” in Figure 7.12 appears.
(6) Perform the same setting in mA-outpout2 if necessary.
Both outputs are 4-20mA

To set the analog output range, follow these steps:
(1) Select the Setup from the Execution/Setup display.
(2) From the Commissioning (Setup) display, select the “mA-output setup.” Select “mAoutput1”
from the “mA-outputs” display. The “mA-output1 range” that displays “Parameter: Humidity,”
as shown in Figure 7.10 then appears.
