Electronic Continuity Test Kit, 9V Buzzer Circuit Tester With LED Indicator Light, For PCB Cable Wire Testing 100DB Sound Alarm(C)

• [BUZZER SOUND PROMPT] The 9V Buzzer Tester features a loud buzzer sound prompt at approximately 100 decibels, ensures clear and immediate during testing. This makes it for use in noisy environments where visual indicators alone may not suffice.
• [VISUAL INDICATOR LIGHT] Equipped with an indicator light that provides visual confirmation of wire conductivity, allowing for quick and easy identification of issues without the need for extensive troubleshooting.
• [USER-FRIENDLY OPERATION] Simply in the tester and touch the two ends of the wire to check conductivity. If the buzzer sounds and the light activates, the wire is functioning properly, making it accessible for users of all skill levels.
• [REPLACEABLE for battery] This product includes a built-in 9V for battery that can be easily replaced by opening the cover. This ensures long-term usability without frequent replacements or downtime.
• [PACKAGE OPTIONS] Available in multiple for configurations including just the continuity tester or bundled with clip wires and multimeter pen wires, providing flexibility to meet various testing needs.

Features: The product has a buzzer sound prompt, and the volume is about 100 decibels. It also has an indicator light prompt. 1. How to use: After plugging in the test , touch the two ends of the measured wire. If an audible and visual alarm is issued, it means that the wire is conducting, otherwise it is not conducting. 2. This product has a built-in 9V for battery, and the cover can be opened to replace the for battery. As shown in the principle diagram, if the red and black ends are not measured, the is not conducting and there is no current consumption. 3. After the measurement circuit is turned on, the loop current is about 20ma. This product is not suitable for measuring tiny electronic components, electronic circuit , .
