What tools can quickly test electronic components?

A very useful tool the ST-10B tester tweezer. The open & short and LED tester tweezer.
At beginning that is handmade tooling for sales representative who using it to demonstrate the LED lighting at illumination LED push button switch for the customer.
The tester tweezer function includes check conductive contact open & short such as push button switches contact, relay, fusor, wire cable etc. by the ring LED light or buzzer.
Light up LED check LED Light-emitting color, through slider switch switching current to power on the LED also identify positive and negative side of the LED pin.
Through test leads connect to Digital Multimeters (DMM) or LCR meter it become SMD test probe tweezers for measurement.

Operating instruction for LED & Conductivity Tester Tweezers

ST-10B built-in LED ring green light and buzzer provide immediate visual and audible test results, making them intuitive and clear. The grooved grip ensures a comfortable fit for the user's fingers, ensuring stable operation. It also comes with a connecting cable and jack, allowing you to connect a multimeter and check the readings with one hand.

Information for ST-10B and option part - Precision Kit

Testing tweezers is like holding a pen, one-handed operation. Even you can use accessories K-ST-10B-01 precision kit for tiny SMD components (0402 and 0201).
