Source Units
This will display the engineering units that have been determined from the
transmitters referenced by the expression. As long as there is just a single
transmitter, or all transmitters share the same unit type, then this will show the
engineering unit here. If the engineering units cannot be determined by the
expression you entered, or you just want to override it, you can enter your own text
instead.
Working Units
When the Units (Entered above) are recognised then on tapping this section you
will be presented with a list of engineering units that the displayed value can be
automatically converted to. See
. The selected working units will
be used when the tile refers to your entered colour change thresholds.
If the Units are not recognised you get the option of choosing your custom text to
display.
In all cases you can choose to display no units by selecting None.
Colours and thresholds
Enter two threshold values which will determine the colour of the indicator. When
the value is less than the first threshold the first colour will be used. When the value
is greater or equal to the first threshold and less than the second threshold the
middle colour will be used. When the expression value is greater or equal to the
second threshold the third colour will be used.
