Recorder Output
(terminals 1, 2, 3)
These contacts are used for connec-
tion to a recorder output. The output
can be 0-20 mA or 4-20 mA and is pro-
portional to the measured Dissolved
Oxygen values.
Connect the “+” wire from the recorder to terminal 1 on the instru-
ment and the other wire (common) to terminal 2 for 4-20 mA re-
corder output or terminal 3 for 0-20 mA recorder output.
Note:
Only one recorder output connection is permited. In order to avoid
malfunction leave unconnected the unused terminal.
