UT681HDMI Cable Continuity Tester

Check basic HDMI cable wiring before replacing the connected equipment. The UT681HDMI tester provides indications for supported continuity, open, short and crossed-connection checks in a portable tool.

✅ Find a basic connection fault in the cable - The wiring checks help identify a cable connection that is open, shorted or crossed.

✅ Read the check on the tester itself - LED status indications keep the result at the test point without a separate computer display.

Start the Investigation with the Lead

When an HDMI connection is not working as expected, a basic cable check gives you another reference before changing the source or display. Record the indication and compare it with the tester's guide for the next inspection step.

Use the tester with disconnected cables and follow the instructions for its actual connectors. Continuity does not certify the cable's supported video format or bandwidth, so a working wiring result is one part of the investigation rather than a complete signal-performance test.
