What is the difference between the "System Info" screen and the "Check Switch" test?

[psnarula]

I have a 105 superdish and a 625 receiver. If I do Menu > 6-1-3 (System Info), box (g) gives me two green bars underneath 119 and 110 but a red X under 105.

however, the "Check Switch" under the Point Dish screen (Menu > 6-1-1) tells me that I have six green "OK" marks so everything there seems to be normal.

is this expected behavior?

The system info screen is a bit more finicky than the check switch. The check switch test will look longer for an acceptable signal.
My system info screen fails out the 148 for me half the time, but check switch is fine with it. Just means I have a low signal strength. It locks, but is low or takes some time to lock in.

the details just tell me i've one signal loss in the last six hours (and that's when i unplugged the box for a second).

derwin0's answer is good enough for me.
