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.

Sensor Zero Adjustment
The sensor zero adjustment will either add or
subtract a bias value to the zero point, which will shift
the entire curve by this value. The slope of the curve
is unchanged.
The current sensor reading can be seen in the pop-up
window and is adjusted by pressing the up and down
arrows. When the reading is correct press the enter
button to store the adjustment.
The amount of zero offset adjustment currently
being applied to the sensor is shown in the channel’s
calibration menu.
