How to use

Connect one end of the HDMI cable to the tester's main unit and the other end to the remote/loop connector if provided, or attach the appropriate adapter where required. Power the unit using its internal battery and initiate the test according to the device's control (single-button or switch). Observe the visual indicators to determine if each pin is continuous, shorted or miswired. If the results show faults, retest with known-good cables or inspect connectors for damage, bent pins or improper soldering.

Recommendations

Use the tester in dry, indoor environments and avoid applying excessive force to HDMI connectors. For ambiguous results, verify with a second known-good cable or inspect connectors under magnification. Replace batteries before extended diagnostic sessions to ensure reliable readings.
