Channel Setup
Mode
Selecting off-line causes any setpoints associated
with this channel to de-energise. Also causes any
current outputs associated to hold their current
value, useful for when commissioning or calibrating
the instrument.
When the unit is placed in an off-line state “off-line”
will appear in the channel messages section on the
front screen.
If a “Cannot Edit Digital Input Has Control” message
appears, then an associated digital input is currently
controlling the on-line / off-line state of the channel.

Units
The channel can be setup to display the reading with
the following units: NTU, FTU, mg/l, g/l, ppm, ppt,
EBC, OD and %.
The relationship between these units and the
incoming probe signal is determined by the
linearisation curve data (see page 14) and range
setting (see next item). They provide a qualitative
rather than quantitative representation of the solids
present in the sample for display purposes and
setpoint / current output processing.
Optionally the instrument can be configured to work
only with the raw probe units by setting the units to
PS.
