>
The Estimated TA (Time of Arrival) and Actual TA show
the theoretical and measured transit times. These values
should be within several per cent of each other. If the
actual value is displayed as 9999.99 then a usable signal
could not be detected.
The gain on line one is an indicator of the signal strength.
A good signal should have a gain of between 600 to 970.
The number in parentheses is the switch setting and
should be x1 or x10. Gains of X100 show that the
received signal is too small to be used.
The second line shows the current time differential
between the upstream and downstream signals.
The unit’s software version is shown on line 1.
Line 2 shows the unit’s serial number.
This screen will be displayed if the Pulse output is on,
and show data related to the mode of operation. This
includes a live display of the Frequency output.
