213: Continuity Tester
Test electronic and electrical circuits
Audible resistance indicator
555 IC & piezo transducer
Easy-to-understand student manual
This handy tester is an excellent beginner's project. The clear, well-illustrated manual makes learning electronics fun and easy. Step-by-step assembly instructions ensure that every student will have a successful experience.
The student learns the history, operation (monostable and astable) and applications of the versatile 555 Integrated Circuit, as well as piezo transducers, by performing experiments while assembling the kit.
The tester checks circuits for shorts, low resistance, high resistance, and opens. An audio tone varies in frequency with the circuit resistance. Low current flow ensures that the circuit under test will not be damaged. Requires one 9V battery (not included).
Battery: Alkaline 9 Volt (P/N: BAT-9V)
