2. Loop Analysis
Loop analysis is a measurement method that summarizes
and automates the most important measurements, in order
to simplify and speed up the test sequences. In the main
menu you have to set the measuring aid to be used.
You can choose between:
KE90X
(with acknowledgment of switching commands)
TX915
(reduced functions)
or
Manual
(manual switch).
2.1 Loop Analysis w/o CO
The loop analysis without the exchange refers to a recently
released line that is separate from the central office.
Measurement method
Connect the wires to be measured and the shield of the
cable. Select
Loop analysis without C.O.
and press
SEL
.
The measurement starts automatically thereafter.
Follow the coming instructions shown in the display.
First every measuring point combinations (A-B, A-GND and
B-GND) successively established the current levels of direct
and alternating current, followed by the measurement of the
DC and AC voltages, the resistance measurements and the
length resulting from the resistance, capacity, the length
resulting from the capacitance and finally the insulation
resistance.
With
F4
Stop, the measurement can be frozen and then left
completely with
ESC
.
After the measurement has been completed, a QR code with
the measured values can be generated and displayed with
F3
QR code. This can then simply be read in with a QR
application.
ESC
exits the view and test.
Alternatively, the measured values can also be stored as a
CSV file under
F4
for later evaluation.
