8. Setting Operating Parameters - Detail,
and Examples
8.1 Setting Analog Outputs
8.1.1 Analog Output Range (Per-Channel)
The analog output range is defined by setting the oxygen concentration value corresponding to the
range minimum oxygen concentration (corresponding to 4 mA output) and the oxygen concentration
value corresponding to the range maximum oxygen concentration (corresponding to 20 mA output).
For each channel the range settings can be set independently. You can have two ranges for each
output, switched by contact input: Contact OFF results in Range 1, and contact ON results in range
2. For details, refer to Section 8.4 Setting Contact Inputs. Factory default setting is 0 to 25% O
2
for all
ranges.
<Setting Procedure>
1) Touch the Setup key, and the [Execution/Setup] display appears.
2) From the [Commissioning] display select [mA-output setup] then [Set range]. (See Figure 8.1).
3) Use [ ] and [ ] keys to select the channel.
4) Set [min] O
2
concentration corresponding to 4 mA output, then set [max] O
2
concentration
corresponding to 20 mA output (select, then touch the Enter key).
5) The numeric data entry display shown in Figure 8.2 appears; enter the desired oxygen
concentration setting. To set 10% O
2
, input [010] and touch the Enter key.
6) As necessary, repeat for averaging output a, b and c and other channels.
