You need to hit the FULL/EXPAND button and also Gain to get up to ca 4km or so....
5.1 Connect the pair under test to the LINE sockets using one of the test leads provided.
(Normal operation only requires the use of the LINE terminals. For information on the
REF sockets see section 7).
5.2 Switch the Tester ON by depressing the ON button. The display should appear on
the screen.
5.3 Adjust the CONTRAST control to obtain a bold, clear display.
5.4 Observe the trace display for evidence of a reflected pulse.
5.5 Adjust the Tester sensitivity by using the GAIN + and GAIN - controls to obtain a
clearly visible reflected pulse. The BALANCE control can be used to position the
trace on the screen at high GAIN settings
5.6 Move the cursor by using the left and right, fast and slow cursor buttons and set it to
the point where the reflected pulse just departs from the horizontal (figures 2 and 3).
5.7 Depress the FULL/EXPAND button to obtain the expanded trace, which is confirmed
by the word EXPAND replacing the word FULL on the screen.
5.8 Use the cursor left and right controls to accurately position the cursor.
5.9 The distance to fault in metres is displayed on the screen. REMEMBER TO DEDUCT
THE LENGTH OF THE TEST LEAD.
5.10 If the fault is close to the near end and the reflected pulse cannot be clearly identified
then refer to section 6.
5.11 Revert to FULL display by using the FULL/EXPAND button to test another pair.
I'll email you some manuals... Done
EDIT: the other thing is that on an ECI cab even a JDSU I've had on mine can't see the Cab/DLM.... There is apparently no 1Hz beacon transmitted like the Huawei cabs do...
The trace attached is showing just the area within the square box at top left... and the one below that is the full trace
