Turning The Cable Detector On (Signal Transmitter + Receiver); Continuity Test; Status Test On Telephone Lines - VOLTCRAFT LSG-4 Mode D'emploi

a) Turning the cable detector on (signal transmitter + receiver)
• The functions of the signal transmitter in the DMM are activated/deactivated via buttons (3 and 13).
• When the button is pressed, the corresponding function is on. To turn off press the switch again.
• The receiver is activated with the rotary switch (20). The receiver is switched off when the switch (with snap func-
tion) is in the "0" position. Position 1 – 9 corresponds to the volume (1 = low, 9 = high).
Prior to working with the cable detector, you first have to insert the enclosed batteries. Inserting and chang-
ing the battery is described in the chapter "Maintenance and cleaning".
b) Continuity test
Continuity tests can be performed with the banana clips (14) on the signal transmitter. Resistance values of <10 kOhm
are signalled optically.
Proceed as follows to perform the continuity test:
1
• Release all push buttons (2, 3 and 13) to return them to the OFF position.
• Activate the function "continuity test" by pressing the button "Cont" (13). The
button snaps into place.
• Connect the two banana clips (14) with each other for testing. The display
"L1" turns green. It goes off after separation of the clips.
• Connect the two banana clips with the lines to be tested. With a forward resistance of <10 kOhm, the display "L1"
starts to light up. The smaller the resistance, the brighter the light.
• Terminate the continuity test and press the button "Cont". The continuity test is switched off.
c) Status test on telephone lines
In passive state, the signal transmitter functions as a status tester of telephone lines carrying voltage. The polarity (right/
wrong) as well as an incoming ring tone can be displayed. The max. input voltage is 50 V.
Line status with banana clip
1
• Release all push buttons (2, 3 and 13) to return them to the OFF position.
• Connect the red banana clip with the connection "Lb" and the black clip with the connec-
tion "La".
• In case of correct polarity, the display "L1" (1) lights up green. If the polarity of the connec-
tions 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 telephone connections.
