This photo taken with camera near pavement angled up.FSC and sensor are just barely visible behind the lowest part of the bumper trim.
We want to get an accurate "overnight low" and this is a good location for that.
Viewed straight on, FSC can't be seen.
Let's look at the monitor. The upper digital readout is the monitor's own temp sensor (vehicle interior).Channel select 1 then 2 then 3 and watch lower readout.
#1 is our exterior front location and we expect lowest of all readings there.
#2 is our underhood and clearly we expect higher readings.
#3 no sensor at this time
