Channel Calibration
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.
