The output ranges (two ranges) of each channel are independently settable. Ranges are
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. Shipping time default is
for each range to be set to 0 to 25% O
2
. The ratio of the maximum range setting to the
minimum is restricted as described in Sec. 8.1 Setting Analog Outputs.
1) Touch the Setup key to switch to the [Execution/Setup] display.
2) From the [Commissioning] display select [mA-output setup], then [Set Range]. (See
