Line Insertion Loss measurement @ 820Hz, 3kHz, 40kHz, 100kHz, 150kHz, 300kHz.
Line Looping (used for PET distance calibration and for Varley Bridge Fault Location)
Foreign Battery measurement (A-B,A-GND,B-GND) and Line Voltage measurement.
The new improved Digital Line Test Set is now available for immediate delivery. The TX120 Series is both a time and money saver, which combines the functions of several instruments into one comprehensive piece of equipment.
The TX120 Series includes all the functions of the upgraded Loop-a-Line used for Pair ID, remote line looping, exchange, connect/disconnect plus external terminals for line access to fault finding test instruments eg. PET, CZ3000.
Since its introduction to Telstra in 1997, the TX120 Series has found world wide acceptance, with well over 1,000 units supplied.
THE TX120 SERIES CONSISTS OF:
TX120 SERIES RECEIVER
Supplied with clip test lead.
Siemens Series 71 test lead.
Siemens Series 2000 test lead
Siemens Series 5000 test lead
Exchange power lead
