If the test failed because of different lengths
of measured pairs following items are
displayed:
- the sign
- the length of the displayed pair
length test failed
By using the
key it can be switched between length and amplitude. Before amplitude
the pulse
length (short , middle , long ) is displayed for 0.5s.
By using
and keys the lenghts or amplitudes of other pairs are displayed.
Note
(If different pair lengths were measured with different pulse lengths differences in
amplitude can occur. The operater must consider this effect when comparing
amplitudes.)
If the length test (lengths of measured pairs
are not differ for more then 5%±0.5m)
passed succesfully but additional (one to
three) reflections are detected following
items are displayed
- the
and
signs
- the length of the displayed pair
length test successfully passed, additional reflections
are detected
If the length test fails and additional
reflections are detected following items are
displayed:
- the and signs
- the length of the displayed pair
length test failed, additional reflections are detected
By using
and keys the lengths of other measured pairs and reflections are
displayed.
By using the
key it can be switched between distance and amplitude. Before
amplitude the pulse length (short , middle , long ) is displayed for
0.5s.
Some typical subresult screens are shown below:
amplitude of length of pair 3,
additional reflections are detected distance to the exessive reflection
