Frequently Asked Questions - CT20TDR VOLTCRAFT

How to turn on the cable tester?

Press the on/off button (5). A beep sounds (if enabled). The screen displays 'SELECT MODE'. To turn off, press the same button again. The device turns off automatically after 5 minutes of inactivity (30 minutes in TONE mode).

How to test a LAN cable?

Connect the cable to the RJ-45 MAIN jack (3) and, for a loopback test, to the LOOPBACK jack (1). Turn on the device and press the LAN button (20). Press TEST (9) to start the test. The result displays: PASS or FAIL with fault details (OPEN, SHORT, CROSS, SPLIT).

What do PASS and FAIL results mean?

PASS indicates the cable is correct. FAIL indicates a fault: OPEN (break), SHORT (short circuit), CROSS (cross-wiring), SPLIT (split pairs, minimum length 1 m). The affected wires flash on the screen.

Which battery to use for the CT20TDR?

Use a 9 V monoblock battery (non-rechargeable). Observe polarity when inserting. Replace it when the empty battery icon flashes.

How to change the battery?

Loosen the screw of the battery compartment (10) with a Phillips screwdriver. Remove the cover, disconnect the old battery and connect the new one respecting the polarities. Replace the cover and tighten the screw moderately.

How to calibrate the length measurement?

In the SETUP menu (8), select LAN Length Adj or COAX Length Adj. Connect a cable of known length to the MAIN (3) or F (2) jack, measure with TEST, then adjust the value with the navigation buttons. Save by holding MEMORY for 2 seconds.

Can I test live cables?

No, absolutely not. The cable tester is designed only for de-energized installations. Measuring live cables poses a life-threatening danger and may damage the device.

What to do if the device does not turn on?

First check the battery: insert a new 9V battery respecting polarity. If the device still does not turn on, contact a technical service. Make sure the battery compartment is clean and the contacts are in good condition.

How to clean the tester?

Use a soft, antistatic, lint-free cloth. Do not immerse the device in water and do not use abrasive or chemical products.

Where to find the complete manual for the CT20TDR?

The complete manual is available free of charge in PDF format on the website notice-facile.com. You can download it by selecting your language and providing your email address.
