New improved continuity tester with louder buzzer.
A decent continuity tester is one of those esscential pieces of test equipment every hobbyist and professional alike need in their tool kit. Although most multimeters have a resistance range not all have a buzzer or the ability to select a low and high resistance range.
Our two-range continuity tester kit will buzz up to 3 Ohms on the LO range and up to 285 Ohms on the HI range. The instructions supplied also explain how you can set your own ranges by changing resistor values connected to the LM324 quad op-amp IC.
Ideal beginners or school project. Full circuit description provided. Box supplied houses PP3 battery (not included). Supplied with alligator clip leads shown but can used with your preferred probes.Specifications
