The TGT current value corresponds to the pointer position on
the scale and is readable to a 1.0 “C resolution.
If the
actual data goes above 1000 “C, the pointer remains stationary
at the upper arc limit and the digits show the actual TGT
value.
TGT exceedance (amber/red regions) is shown by growing the
colored band to twice the normal width and changing the pointer
and current TGT digital value (normally white) color to match
the arc region color.
