Cable tester for audio and data connectors

The Hosa Technology CBT-500 diagnoses signal failure in cables fitted with XLR, Phone, Phono, speakON®, DIN, Ethernet and USB Type A to Type B ends. Removable leads extend continuity checks to additional contacts and jacks. Technicians and installers use it to verify wiring integrity before or after deployment. It suits anyone who needs a single tool for multiple cable families.

Battery powered operation with audible feedback

A 9-volt battery is included and powers all test functions. Cable test mode steps through each contact position as the knob is turned. Continuity mode illuminates a centre LED and sounds a beep when a circuit is complete. Battery check position lights the LED to confirm remaining charge.

Included battery and removable leads expand utility

The supplied battery allows immediate use without a separate purchase. Removable leads let the operator probe contacts that do not match the built-in jacks. This combination means the tester covers both standard terminated cables and bare-wire or custom connector checks.

Questions about this item

How do I install the 9-volt battery in the CBT-500 and what step is often missed?

The battery compartment opens on the rear; insert the included 9-volt cell observing the polarity markings, then close the cover fully so the contacts seat — skipping the cover latch is the step most users miss.

What maintenance will the CBT-500 need over time?

Replace the 9-volt battery when the Battery Check LED no longer lights; the removable test leads should be inspected for bent tips or cracked insulation and swapped if damaged.

What limit appears first when testing many cables in one session with the CBT-500?

Battery voltage drops during extended use, causing the Battery Check LED to dim and the continuity beep to weaken before the tester stops indicating faults correctly.
