D) Signal Tracking - VOLTCRAFT LSG-4 Bedienungsanleitung

Line status with modular plug
- Release all push buttons (2, 3 and 13) to return them to the OFF
position.
- Connect the modular plug with a modular telephone socket until the
plug snaps into place.
- In case of correct polarity, the display "L1" (1) lights up green. If the
polarity of the connections is mixed up, the display lights up red. In
case of an incoming ring tone, the display blinks in the interval of the
ring tone. Attention! Danger of an electric shock when touching this
signal voltage!
- When the test is completed, remove the banana clips from the tele-
phone connections.

d) Signal tracking

With signal tracking, you can determine the path of all cables, conductors or metal pipes not carrying
voltage. An acoustic signal is applied to the line to be tested. This signal can then be located with the
receiver and the line path checked. It also serves to identify lines in installations etc. The signal is emit-
ted simultaneously on the banana clips and the modular plug.
To track the signal, proceed as follows.
- Release all push buttons (2, 3 and 13) to return them to
the OFF position.
- Activate signal tracking by pressing the button "Tone"
(3). The button snaps into place.
- Turn the receiver on at the rotary switch (20) and select
a volume of approx. 6-7.
- To perform the function test, put the tip of the receiver
(21) on the banana clip or the modular plug and keep
the button (19) depressed. A wobble sound is emitted.
- Select the desired test signal with the switch "Sel" (2). When the switch is depressed, a permanent
sound is emitted, when it is not pressed, a wobble sound is emitted.
- Use an optional set of headphones, select a lower volume. The headphones can be attached to the
jack socket "Phone" (16). For signal tracking with headphones, it is not necessary to press the but-
ton (19). The headphone socket is always on in activated state.
- Put the banana clip or the modular plug on the lines to be tested.
1. With cables that are connected at one end, please use the shielding or ground potential for the
black clamp. Attach the red clamp to the internal conductor.
