Continuity Test On Co-Axial Cables; Polarity Test On Telephone Cables - VOLTCRAFT LSG-3 Mode D'emploi

Continuity test on co-axial cables

Co-axial cables can be tested for function/damage in the same
manner, .
Make sure before connection that the cables are not live
(danger to life).
• Turn the switch-over for testing mode (22) to the central position
"OFF".
• Connect the two test terminals (24) using the cable to be tested.
• Switch the switch-over (22) to the left in the position
"CONT/Talk". The pushbutton (20) may not be pressed.
• The green LED display (21, line2/continuity) displays the continu-
ity status:
• Time-phased coaxial cable Connect the red test cable (24) to the
inside line and the black cable to the outside line/shielding. The
display (21) must light up.
• Open co-axial cables. Make the test connection as for time-
phased cables. The display (21) may not light up.
• Turn the switch-over (22) after the end of the test to the central
position "OFF" again.

Polarity test on telephone cables

Telephone lines can be tested for correct polarity using the net ton-
er. The net toner can test two connection standards; line 1 = con-
tacts 4/5 or line2 = contacts 3/6
Make sure before connection that the voltage on the
cables is not greater than 48C DC or 24V AC (danger to
life).
• Turn the switch-over for testing mode (22) to the central position
"OFF".
