Continuity test, general
The net toner can be used as an optical continuity tester.
Make sure before connection that the cables are not
alive (danger to life).
• Turn the switch-over for test mode (22) to the central position
"OFF".
• Connect the two test terminals (24) using the cable to be tested.
• Turn the switch-over (22) to the left to the position "CONT/Talk".
The pushbutton (20) may not be pressed.
• The green LED display (21, line2/continuity) displays the continu-
ity status:
brightly lit = little cable resistance
medium-lit = high cable resistance
not lit = interrupted current circuit
• Turn the switch-over (22) after the end of the test to the central
position "OFF" again.
If the ends of the cables to be tested lie too far apart, use
a second reference lead for a return path. Wire these two
cables together at the end furthest away.
