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 corre-
sponding 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 Sec. 8.5 Setting Contact Inputs. Factory default setting is 0 to 25% O
2
for all
ranges.
1) Touch the Setup key, and the [Execution/Setup] display appears.
2) From the [Commissioning] display select [mA-output setup] then [Set Range]. (See
Fig. 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 Enter key).
5) The numeric data entry display shown in Fig. 8.2 appears; enter the desired oxygen
concentration setting. To set 10% O
2
, input [010] and touch Enter.
6) As necessary, repeat for averaging output a, b and c and other channels.
